the following circuit, again driven with a source having 500 source resistance and
connected to a differential load capacitor of 40 ff (equivalent to 80 ff on each side). I
do not show the full differential circuit and I did not worry about whether the transistors
were NMOS or PMOS in the circuit. Once again, assume that these transistors have
gm=1mA/V, with the capacitances listed in Q1.
a. Estimate the 3dB bandwidth of this circuit.
b.
Compare the BW of this circuit to those calculated in Q1 and Q2 and comment
on the differences observed. Does this circuit have a wider BW? Why?
