4 cards from this section. Quick, good the night before a test.
What is the function of a differential pair in an op-amp?
Think about what it means to amplify the difference.
Define open-loop gain.
Consider the amplification that happens in an op-amp without any feedback mechanism.
What is the primary function of a differential pair in an op-amp?
Think about what it means to amplify the difference.
True or False: High CMRR is important for an operational amplifier.
Consider what happens when common signals are amplified along with the desired signal.
Design a basic CMOS op-amp using NMOS and PMOS transistors while defining the values for open-loop gain and input/output impedance that would meet typical application requirements.
Think about how transistor configurations will affect your gain and impedance.
Given the open-loop gain of an op-amp of 1500 and a common-mode gain of 50, calculate the CMRR and discuss the implications on the amplifier's noise rejection.
Use the CMRR formula as a guide.
