Find the mid-band gain AM and the 3-dB (high) frequency of a MOS cascade amplifier as shown in the following circuit.

The MOSFET device parameters are as follows:

(Consider M1 and M2 are the same.)

gm= 1.2 mA/V, ro= 100 kΩ; Cgs= 20 fF, Cgd= 8 fF, and Cdb= 10 fF.

The source has a large Rsig =50 kΩ. On the load side, RL= 2 M, and CL= 50 fF.

(Hint: This problem uses cascoding resistance in time-constant method for calculation of high corner frequency.)
