ECE 3042 Homework Assignment No. 4 Spring 2010 Homework for Experiment No. 4 Due Week of February 15 1. Shown above is an op amp differential amplifier with a floating source input. Design this op amp differential amplifier to have a differential gain of 7 . 3 and a differential input impedance of 2k . Assume that R o is zero for the design calculations. Use either Cadence or National Instruments SPICE (Multisim) to perform a transient analysis of this amplifier if the inputs are two single ended sources instead of the floating source. For the two inputs to the amplifier use v 1 ( t )= A 1 sin( ω 1 t + φ 1 )+ v sq ( t ) and v 2 ( t )= v sq ( t ) where A 1 = 322 mV , f 1 =1kHz , φ 1 =45 ,and v sq ( t ) is a symmetric square wave with a peak to peak value of 8V , a frequency of 4 kHz , and makes the transition from the lower level to the upper level at t =0s . Plot the output voltage as a function of time for 0 <t< 3ms . Use SPICE to perform a harmonic analysis (the frequency spectra) of
