48.2. Conclusion on Circuit Design

So, unnecessarily, we should not be putting this R. So, that is what the conclusion. So, let us see what is the design guidelines we can follow based on this knowledge?

In this part of the conclusion, we emphasize the importance of not adding unnecessary resistance (R) to the circuit design. The key takeaway is that we should focus on the essential components needed for an effective design without complicating the circuit unnecessarily. This sets the stage for discussing specific design guidelines that will help practitioners create better circuit designs based on the learned principles.

Think of designing a car. If you add too many features that do not enhance the driving experience, it could make the car cumbersome and complicated. Just like car design, in circuit design, simplicity and functionality are key to success.

So, the summary of the design guidelines is that we start from output resistance particularly for common drain circuit... So, it boils down to the point that we need to calculate the corresponding R of the circuit.

This chunk outlines the structured process for designing circuits like the common collector and common drain types. The process starts with understanding the output resistance requirements. From there, you derive other essential parameters like transconductance (g) and corresponding current (ID) needed to achieve design goals. This systematic approach ensures all desired characteristics of the circuit can be met efficiently.

Imagine a chef preparing a recipe. The chef first gathers the ingredients (output resistance) based on the recipe (design requirements), then measures and mixes them (calculating g and ID) to produce the intended dish (the finished circuit). A clear order of operations results in a better outcome.

Similar kind of guidelines it can be followed for the common collector circuit also. Where, again the information may be given or rather requirement it will be given for the upper cutoff frequency for a given load capacitance.

In this section, we relate the design principles of the common drain circuit to that of the common collector circuit. Similar guidelines apply, emphasizing the importance of knowing parameters like cutoff frequency and load capacitance to calculate necessary resistances and currents. Understanding this relationship simplifies the design process and reinforces a cohesive understanding across different circuit types.

Consider two different styles of bicycles: a mountain bike and a road bike. While they serve different purposes, both require the cyclist to adjust gears and brakes according to the terrain (similar guidelines for different circuits). By learning how to adjust one type, a cyclist can quickly learn to adjust the other effectively.

I think we need to conclude now. So, what we have done today? It is we are we have concluded with numerical examples... In the next class; we will be going for the other configuration namely the common base and common gate configuration.

This concluding part recaps the lessons learned during this session. It's essential to reflect on the numerical examples provided, reinforcing practical application of the theoretical design guidelines discussed earlier. Additionally, it hints at upcoming topics that will expand on circuit designs, leading students into the next phase of their learning journey.

Think of a lecture on different types of cooking techniques. When the session concludes, the chef recaps the techniques learned with examples (numerical examples) and then introduces the next class focusing on advanced techniques in gourmet cooking (common base and common gate configurations).
