#1. cascade amp in p.1-12
(1)find Av, Gv
(2)find Ri Ro Avo
#2. For a voltage amplifier with Ri=10kΩ,Ro=10Ω,Avo=20,find its
current/transimpedance/transconductance/amp model.
#3. find find T(jω)=? is it a STC?
Vi‧─-^^^^─| |─┬─┬‧Vo

#4. low-pass STC R=10kΩ,C=10^-6F,
Vi(t)=5cos(t+20°)+8cos(10t)+2cos(1000t-30°)
(1)find Vo(t)?
(2)estimate Vo(t) by Bode plot!!
