Document Summary
Guidelines: open book and notes, the values of common parameters are listed at the beginning of next page. The small-signal parameters for the transistor m1 are: gm = 0. 1 ms, ro = 100 k , rs = 1 k , rl = 100 k , cgd = 10 ff, cgs = 100 ff, Cdb = csb = 10 ff: [10 pt] what is the small-signal voltage gain of the amplifier, [5 pt] draw the circuit with all parasitic capacitances. Rl (2) the following is a two-stage amplifier. Use the following parameters for this problem: ncox = 100 a/v2, pcox = 50 a/v2, (w/l)1 = 10, (w/l)2 = 20, (w/l)3 = The threshold voltages are vth = 0. 4 v for nmos and - Ignore channel length modulation: [15 pt] find the dc voltage of the output node, vout (hint: find the dc voltage at node x first, [15 pt] find the expression and the numerical value of the total voltage gain.
