For the two-stage opamp of Fig. 6.3, assume that the input bias current is reduced to , all transistor sizes remain the same, and .

a. Estimate the dc gain of the opamp.

b. Estimate the –3-dB frequency of the first stage.

c. Estimate the unity-gain frequency of the opamp.

d. Find the slew rate.
