Unformatted text preview: The following circuit illustrates two types of current mirrors. Use PSpice DC runs varying Vdd near 5V to obtain the desired results. a) With parameterized Rin for 100 ≤ Rpar ≤ 100K in logarithmic steps, 1 curve per step, determine the resulting currents into Mn, and Mn2 as well as Mp1 and Mp2 (Show the IDn’s in one plot and the IDp’s in another) b) Over the same range of Rin determine the voltages at in, mid, and out c) Since the currents are supposed to be equal, explain why they are not. Rin {Rpar} Vss5Vdc Vdd 5Vdc Mp1 M4007P ss dd in mid out PARAMETERS: Rpar = 1K Mn M4007N Mp2 M4007P Mn1 M4007N Mn3 M4007N...
