1 NATIONAL UNIVERSITY of SINGAPORE Department of Electrical and Computer Engineering EE2005 – Electronics Homework Assignment #9 (Homework Assignment: Do Questions 1 and 2, and hand-in your solutions to your Tutorial Group Representative right after the EE2005 lecture on Tuesday, 27 th Oct, 2009, 1:30pm, LT6) 1. Write down the transfer function that has the following phase response. You may assume the gain is unity and there is no positive zero in the transfer function. (5 marks) 2. Consider the amplifier shown in Fig. 9-2. Assume the BJT has β =100, V A =100V. Use the following model to verify your simulation results: .model nbjt NPN is=3.3e-15 bf=100 rb=62.5 tf=1n cje=0.45p cjc=2p itf=1m xtf=5 vtf=10 vaf=100 (a) Design R E so that the small signal AC gain (A V =v o /v s ) is 10. (2 marks) (b) Design C S , C L and C B so that the f L is 200Hz. (4 marks) (c) Create the netlist for the circuit below. (2 marks) (d) What is your simulated A V and f L ? ( 2 m a r k s ) (e) Supposed Q1 is replaced with MOSFET M1 with the following device characteristics,
