, 10 rad/s
3.33 47.1 GHz
10 rad/s 5.31 GHz The dominant pole is the smaller pole, so it is 5.31 GHz .
f) Construct the Bode plot of the transistor. Clearly mark the scale of both axes. The Bode
plot should show both the low-frequency voltage gain as well as 3-dB bandwidth of the
The low frequency gain on the plot is 20 log 0.975 Page 6 0.22 dB. Problem 3 [15 points]: MOS Devices
3) Below is the cross section of a PMOS transistor:
S G D Gate Substrate
(Body) B a) What is the doping type (n, n+, p, or p+, where “+” means high doping concentration) of
i) Source: p
ii) Drain: p
iii) Substrate (body): n
b) Which carrier(s) are involved in current conduction? (...
