试题 :
1. For the following circuit, find the oscillation frequency (fo in terms of R
and C), and the value of K such that the oscillation just starts. (25%)

2. For the following circuit, in which the inverter is matched. Find the
oscillation frequency (fo in terms of R and C), and the value of K such that
the oscillation just starts. (25%)

3. For the following CMOS inverter, in which R=1MΩ, kn=20μA/V^2, Vt=1V, and
VDD=5V. Find the values of VM, NML, and NMH. (25%)

4. The following circuit consists of matched inverters, in which R=1kΩ, C=1nF,
kn=kp, Vt=1V and VDD=5V. However, the process variation makes the actual kn
increases 1%, that is, kn becomes 1.01kp. In this situation, find the values
of Y1, Y2, and Y3, as Yo is charged to VDD/2. (15%)

5. Sketch the PDNs of the following 1-bit full adder, in which
Cout = AB + ACin + BCin and S = ABCin + (A + B + Cin) Cout'. (10%)
