5) You may assume that the circuit is symmetric (if you don't this becomes hard). Sketch the difference

voltage Vout as Vinl and Vin2 vary differentially from zero to VDD (this is the large signal differential

response). Next assume that Vin Vin are the same and vary between Ov and VDD sketch the value of one

of the Vout nodes (they both will have the same voltage) This is the large signal common mode response.

Label important transitions as above. Additionally derive the small signal output resistance between the

output nodes and the small signal differential gain for each, assuming that all the transistors are in

saturation. In each case write an expression without approximations, and then write the best approximate

expression given our assumed hierarchy of relative resistance values.
