Question 4 a) Figure Q4a shows a common-gate stage amplifier with parasitic capacitors, CD and Cs. Assume that the channel-length modulation, 1 = 0 and body effect, y 30, determine: 1) the input pole frequency, Om, at node X. [7 Marks] ii) the output pole frequency, our , at node Y. [4 Marks] Vo(s) 111) the overall transfer function, where the first fraction represents the low- V (s) frequency gain of the circuit.. [2 Marks] b) Figure Q4b shows a differential pair with active current mirror and feedback circuit. Assume that the body effect, y 0 and channel-length modulation, 1 0. At low frequencies, determine the open-loop gain and closed-loop gain. [8 Marks]
