Question

8.24 Figure P8.24 shows an amplifier utilizing a currentmirror Q,-Q,. Here Q, is a common-source amplifier fedwith v, = Ves + v,, where Vs is the gate-to-source de biasGS voltage of Q, and v, is a small signal to be amplified. Find the signal component of the output voltage v, and hence the small-signal voltage gain v/v,. Also, find the small-signal resistance of the diode-connected transistor Q, in terms of gm2, and hence the total resistance between the drain of Q,and ground. What is the voltage gain of the CS amplifier Q,?Neglect all ros.
