ECE4902 C2009 HW Set 4 Due in class Friday February 13. Note the problem set has been reduced to a compassionate 6 problems since you have an exam Wednesday February 11. You may assume T = 300K unless otherwise indicated. Use the following MOSFET parameters for minimum length (L=1.6μm) devices in the AMI process: Parameter N-channel P-channel Units V t +0.57 -0.93 V μC ox 7.14E-5 2.40E-5 A/V 2 λ 0.081 0.24 V -1 1) [Analysis of common source amplifier with resistive load] v in V BIAS V OUT V DD = +5V R D 40k ! 15 2 V IN C L 100 pF a) Determine the value of V BIAS that will give an output operating point of V OUT = +3.0V. Do not ignore channel length modulation! b) Draw the small-signal model for the circuit. c) Determine the small-signal transfer function v out /v s . d) Determine low frequency gain and the bandwidth (3-dB frequency) and the unity-gain frequency f T . e) Carefully draw the magnitude and phase Bode plot for the transfer function. f) Sketch the total output voltage v OUT vs time when v in = (+0.1V)sin(2 π [1kHz]t) 2)
