why the cascode transistor has high output impedance. can any one provide better resource for its mathematical verification?
many many thanks
the 2nd transistor is a common base amplifier -> its output is on the collector -> high output impedance.why the cascode transistor has high output impedance.
High res CRT monitors used a casc-ode video amplifier for its excellent frequency response - but its high output impedance wasn't so good for driving the CRT cathode capacitance. The better manufacturers followed it up with a complementary pair emitter follower buffer.why the cascode transistor has high output impedance. can any one provide better resource for its mathematical verification?
