Unformatted text preview: Homework 1 Due February 24 Selected Model Values P2.1) Consider an amplifier shown below with the following parameters: 100 kohm input resistance, 30 pF input capacitance, 60 V/V open circuit voltage gain, and 500 ohm output resistance. The source has a source resistance of 20 kohm, and the load is 1kohm. a) Find the DC gain, K. Selected Ans: K = 33.333 V/V b) What is the type of amplifier frequency response? (refer to note set 1, slide 34) c) Find the 3dB corner frequency. Selected Ans: f0 = 318 kHz d) Plot the magnitude of the overall voltage gain transfer function, |T( )| in dB versus . e) Plot the magnitude of the normalized overall voltage gain transfer function, |T( )/K| in dB versus the normalized frequency, / 0. P2.2) Assuming an ideal opamp, a) find the closed-loop gain of the following circuit and b) the input resistance at the point shown. Selected Ans: G = -2.7 V/V, Ri = 20 kohm P2.3) Assuming an ideal opamp, find an expression for the closed loop voltage gain. loop voltage gain....
