Draw a two-stage op amp similar to the op amp in Fig. 6.16 except reverse the polarity

Question:

Draw a two-stage op amp similar to the op amp in Fig. 6.16 except reverse the polarity of every transistor. For example, the resulting op amp should have an n.-channel input pair. Calculate the following parameters: 

(a) Low-frequency voltage gain, 

(b) Output swing, 

(c) Systematic input offset voltage assuming (6.66) is satisfied, 

(d) Common-mode rejection ratio,

(e) Common-mode input range, and 

(f) Low-frequency power-supply rejection ratio from both supplies.
