Challenge Problems
Push your limits with advanced challenges
A circuit designer needs to amplify a weak signal from a sensor to determine its exact amplitude. If using a real op-amp with a gain of 150,000 and a limited bandwidth, how might this affect the accuracy of the measurement?
💡 Hint: Consider how bandwidth relates to the range of frequencies from the sensor.
Explain how using a real op-amp could result in a voltage drop when driving a load, and how a designer could mitigate this issue.
💡 Hint: Think about how you could design around the limitations of real op-amps.
