Basic Amplifier Circuits

Give the order these four amplifiers as a function of the magnitude of the gain from V_in to V_out.  Assume K_n = K_p, and l is identical for all devices.

Highest Gain to Lowest Gain   

C A D B  (transistor connected to Vref2 is a pFET)

Identify the type of circuits above in terms of the basic circuit names given below.    You might need to use one or more number twice.
