Good day, class! Today, we begin our exploration of why analog designers are so essential even in our digital age. Despite the increase in digital technologies, can anyone tell me why we still need analog circuits?
Because analog circuits help in interfacing with the real world, which is mostly analog.
Exactly! Analog circuits process real-world signals, like sound and light. They act as a bridge between digital systems and the physical environment.
But how does that work practically?
Great question! We will learn how different analog blocks, such as amplifiers or filters, need to be carefully designed and integrated to create functioning systems. Letβs remember the term "AMP"βAnalogs Make Practical connections.
Challenges of Interfacing Analog Blocks

Now, letβs discuss the challenges we face when we combine multiple analog blocks. Why do you think these challenges arise?
I think itβs because different components may have different levels of voltage or signal types.
Exactly! This is known as the interfacing challenge. When connecting analog blocks, mismatches in signal characteristics can lead to inefficiencies or failures.
So, how do we overcome these challenges?
We design consideration into the circuit, addressing aspects like gain and input-output characteristics. Remember the acronym "CIRCUIT": Carefully Integrate Respective Components Using Ideal Techniques.

So, the need of analog designer of course, it will be there. So, if you see the fate of this analog electronics it is if it is in particularly in digital era. So, whenever we say the digital era, basically we are saying we do have more and more digitization with progress of time; but then it also has more and more application.
Detailed Explanation
Despite the growing prominence of digital technologies, the significance of analog designers remains strong. In our digital era, characterized by increasing digitization, we are not just witnessing a rise in digital applications but also a concurrent need for analog components. This indicates that while digital systems may dominate, they still rely on analog systems to function optimally.
Examples & Analogies
Think of a digital camera. It captures images as digital data, but the sensor that initially detects light is an analog device. Without this analog component, no digital image could be created.
The Compatibility of Analog and Digital

But then, as I said that along with the digital core the requirement of this analog shell it will be remaining there; and hence the requirement of analog circuits it will be remaining.
Detailed Explanation
This statement emphasizes the synergy between analog and digital systems. While digital technology often takes center stage, the necessity for analog circuitsβreferred to here as the 'analog shell'βcontinues to persist. As digital systems are built, they need analog circuits to interface with the real world, ensuring smooth operation and data acquisition.
Examples & Analogies
Consider a smartphone. The touchscreen (digital) may command the interface, but the microphones and speakers (analog) are needed for sound, showing how both components are essential for the device to function effectively.
The Evolution of Analog and Integration Needs

Of course, you need to be careful while this core portion it is; core portion it is dominating in terms of volume. The nature or the format of this analog shell it may evolve while it needs to be integrated.
Detailed Explanation
As digital technology continues to advance, the structure and design of analog circuits (the 'analog shell') must also evolve to accommodate these changes. This highlights the importance of integration, requiring designers to be attentive to how these analog circuits adapt and work in alignment with their digital counterparts.
Examples & Analogies
Think about how audio equipment has changed. Older systems had separate components (analog) for different functions, while modern audio systems often integrate these functions into a digital framework, requiring designers who can make sure everything works harmoniously together.

To summarize, so before we summarize; so in this context I must say that, what are the; what are the things we are going to covered in this analog electronics, to be more precise what may be the emphasis of this course. We will start with analog building blocks, their working principle, analysis and design and those building blocks.
Detailed Explanation
The course on analog electronics will begin with a focus on analog building blocks. This involves understanding their working principles, how to analyze them, and how to design them effectively. This foundational knowledge is critical for anyone looking to get into analog design, setting the stage for more complex topics that will follow.
Examples & Analogies
Imagine learning to build a house. You start with understanding the basic materials (bricks, wood) before you can build a sturdy structure. Similarly, in analog electronics, we start with understanding building blocks before assembling complex circuits.
Understanding Interface Challenges

So, here we will start with building blocks, different building blocks individually and then we will move to whatever the challenges we will face while we will be interfacing different blocks together to make a bigger system.
Detailed Explanation
Once students grasp the individual building blocks, the next challenge they will face is interfacing these blocks. Each block has its unique properties, and merging them into a complex system poses various challenges that need to be understood for effective design.
Examples & Analogies
Think of connecting multiple musical instruments in a band. Each instrument has its sound and way of playing, and to create a harmonious song, musicians need to understand how to blend their sounds seamlessly. Similarly, in circuit design, understanding how individual components interact is crucial.
Moving Towards Practical Applications

And then we will see that how this interface effects are making it more and more challenging. And then we will make this circuit more towards practical analog modules.
Detailed Explanation
As students work on applying their knowledge to practical analog modules, they will encounter real-world challenges related to interfaces. This will require problem-solving skills to ensure that all components work together effectively under practical conditions.
Examples & Analogies
When culinary chefs create new dishes, they must consider how the flavors of individual ingredients affect the overall flavor of the dish. Designing circuits likewise requires considering how various components interact in real-world scenarios.
System-Level Approach to Learning

So, I should say we will start from this block level, namely bottom and then we will try to see what will be the interface effects. And then we will see that how we can make bigger system and then we will go from top to bottom; we will start from system level and then we will go to the implementation of the smaller level.
Detailed Explanation
The learning process will have two perspectives: starting from the bottom (individual blocks) to understand integration challenges and then moving from the top (system level) to design smaller components effectively. This dual approach ensures comprehensive understanding and practical application.
Examples & Analogies
Think of a city planning process. Planners first design the overall city layout (system level) and then break it down into individual buildings or sections (block level) to ensure everything fits well and serves its purpose effectively.

Now, moving to the conclusion; so what we have done is that, at least we got some idea about what is electronic circuits and what is the typical electronic system consists of and then also we have we got a sense of what may be the fate of analog electronic circuits, particularly in the digital era which is more and more getting dominated.
Detailed Explanation
Concluding this segment, it's important to reflect on what has been covered: an introduction to electronic circuits, the components of typical electronic systems, and the relevance of analog circuits in our increasingly digital world. Understanding these relationships is vital for any aspiring designer.
Examples & Analogies
Reflecting on the importance of analog circuits in a digital world is like recognizing the roots of a tree. While the tree grows tall and strong (digital progress), it still needs its roots (analog circuits) for stability and nourishment.
