Document Summary
Guidelines: open book and notes, the values of common parameters are listed at the beginning of next page. Please use the following parameters for all problems unless specified otherwise: Si = 11. 7, q = 1. 6x10-19 c, (1) the figure below shows the schematic cross section of a cmos device. 0 = 8. 854 10-14 f/cm: [5 pt] please circle all the pn junctions in this cmos device directly on the cross- sectional diagram in your answer sheets. Pmos, vth = 1v for nmos and -1v for pmos, vdd = 5v. oxc = 50 a/v2, = 0. 05 v-1 for nmos and 0. 01 v-1 for n p. 2: [10 pt] find the dc bias voltages, vb and vg, such that the bias current is 100 a. Find the maximum and the minimum output voltages: [5 pt] how does the voltage gain and the output resistance change if the gate of.
