1 NATIONAL UNIVERSITY of SINGAPORE Department of Electrical and Computer Engineering EE2005 – Electronics Homework Assignment #10 (Homework Assignment: Do Questions 1, and hand-in your solutions to your Tutorial Group Representative right after the EE2005 lecture on Tuesday, 3 rd November, 2009, 1:30 pm, LT6) 1. Fig. 10-1 Assume the following MOSFET parameters and ignore body effect: NMOS : K N =2mA/V 2 , V THN =0.5V, C gd =4pF and C gs =1.6pF. a) Select I bias to get overall gain (v o /v s ) of -10. (2 marks) b) Design R A1 and R B1 so that V G,M1 =V D,M1 ? (2 marks) c) Choose all the DC block/bypass capacitor value to have f L equal to 200Hz. (3 marks) d) Can Miller Theorem be applied? Estimate the f U of this amplifier. (4 marks) e) An engineer has commented that the f U can be increased while maintaining the same gain at the expense of more I bias . Comment on the validity of the above statement. (3 marks) f) Create the netlist for this amplifier for simulation. (3 marks) g) What are the simulated gain, f
