Problem 1 The circuit below is a two-stage common-source amplifier. We assume that the n-type MOSFETs operate in saturation regions and are characterized by parameters as shown in the figure below. (a) Find DC operating points for the output of the two common-source amplifiers (Vo1 & Vo2) when the DC operating point for the input of the first common-source amplifier
(V_(I))is
2V. (b) Find the transconductance gain of the two n-type MOSFETs
(gm_(1)&gm_(2)). Note that
gm_(1)is the transconductance gain of the first transistor on the left, and
gm_(2)is the transconductance gain of the second transistor on the right. (c) Find the voltage gain of the two common-source amplifiers (
A_(1)&A_(2)). Note that
A_(1)is the voltage gain of the first amplifier on the left, and
A_(2)is the voltage gain of the second amplifier on the right.
