1 NATIONAL UNIVERSITY of SINGAPORE Department of Electrical and Computer Engineering EE2005 – Electronics Homework Assignment #8 (Homework Assignment: Do Questions 1, and hand-in your solutions to your Tutorial Group Representative right after the EE2005 lecture on Tuesday, 20 th Oct, 2009, 1:30 pm, LT6) 1. Fig. 8-1 A multistage MOSFET amplifier is shown in the Fig. 8-1. You may assume that the body and the source terminals of the NMOS and PMOS are connected together, i.e. no body effect for NMOS and PMOS. You may also assume the following device parameters and all NMOS and PMOS devices are identical: K n =2mA/V 2 , V THN =1V, λ n =0.001V -1 , C gd =0.5pF, C gs =5pF K p =2mA/V 2 , |V THP |=1V, λ p =0.001V -1 , C gd =0.5pF, C gs =5pF a) Design R REF so that the drain currents for M 1 , M 2 and M 3 are 500 μ A. (3 marks) b) Identify the two stage amplifier configuration and estimate the small signal transconductance for transistors M 1 and M 2 . (3 marks) c) Determine the two ports network parameters for the two stage amplifier, i.e. R
