1) The transistor below is a p-channel enhancement mode unit having the
transfer characteristic ID = - 4(VGS - 2.5)2 (mA). If R1 = 300kΩ, R2 =
200kΩ, RSS = 600Ω, RD = 1.6kΩ, and VDD = -25V, find ID and
VDS



Let VBRI 20 V and RZ1 = 20Ω for D1, while VBR2 = 25V and RZ2 = 35 Ω
for D2. Find I and V for the circuit shown below

I (
