Question

Please solve in details and in a clear way.

NMOS and ,. For what 8.91 Figure P8.91 shows a differential factor of 2? with an active load formed by a Wiloneamplif of transis- Wilson current mirror. Utilizing the expressions derived in Chapter 7e the output of the resistance of a bipolar cascode and the out plifier of t terminals identical, show that the differential volta mirror, and assuming all transistors to ge of the Wilson gain A, is given İbit a wiL output given by cuit is Qs nd Q, are ios of the sponding 01 o vo d 0, are 03 2: rated at in 1% VBIAS 0 perated V and v stance, - e gaino input stage? e pnp ge of of the Figure P8.91 approximately by Evaluate A, for the case of ß 100 and v the bias design of the Wilson-loaded

Answer 1

Determine values of transconductance(gm) and output resistance (r0). Then substitute in Ad. It cancbe seen that, the expression of Ad is independent of Q- point bias current Icq.
