Unformatted text preview: ] Since the amplifiers are biased identically and the MOSFETs are identical, the smallsignal parameters for Amplifier-A will be the same as those for Amplifier-B. , , , 2 , 632 S 1 , , , , 100 kΩ b) What is the topology of “Amplifier-A” (i.e., common source, common base, etc)? [2pts] Cascode c) Find the voltage gain, input and output resistance of Amplifier-A. Show both the expressions and the numerical values. You can make approximations in your expression as long as they are within 10% accuracy. [6pts] 1 4126.5 ∞ 1 6.525 MΩ Page 2 d) What is the topology of “Amplifier-B” (i.e., common source, common base, etc)?
