A common-source amplifier is fed with a signal source having a resistance Rsig = 200 k and feeds a load resistance RL = 20 k. The MOSFET is operating at gm = 4 mA/V and has ro= 20 KQ. The device capacitances are Cgs = 25 ff and Cgd = 5 fF. Find the midband gain AM, the 3-dB frequency fH, and the frequency of the transmission zero. The values of 4m, F and the frequency of the transmission zero. A-40, f = 3.459 MHz, f = 127.3 GHz Rsi 200 k Rt = 20 k 84 mA/V r = 20 kQ Cgs = 25 fF Cad = 5 fF gd
