Unformatted text preview: Student’s Name: PROBLEM 1 (25 points) A diode-connected MOSFET is driven by a DC current source, I X =0.25mA. μ n C ox = 90 μ A / V 2 λ = 0.1 V − 1 V Th = 0.7 V W = 5 μ m L = 0.5 μ m A. Is the MOSFET M 1 operating in triode or saturation ? Why? B. Solve the DC operating point and all small-signal parameters for this circuit: Utah State University page 1 of 6 ECE 3410 - Microelectronics I Midterm 3 TEST M 1 I x v G β = V ov = V G = r ds = g m = 1/ g m = C. A small-signal input, i in , is added to the current source as shown. Calculate the MOSFET’s equivalent small-signal resistance and give an ex- pression for the small-signal waveform v g (t).
