10.9. Consider the amplifier of Fig. 10.74 , where ((W)/(L))_(1-4)=(50)/(0.5) and I_(SS)=I_(1)=0.5mA.
(a) Estimate the poles at nodes x and Y by multiplying the small-signal resistance and capacitance to
ground. Assume that C_(x)=C_(Y)=0.5pF. What is the phase margin for unity-gain feedback?
(b) If C_(x)=0.5pF, what is the maximum tolerable value of C_(Y) that yields a phase margin of 60\deg for
unity-gain feedback?
