Electronics, Example 6 (2Stage, A*))

 

Design a Two-Stage BJT Amplifier (Parameters to optimize RE1, RC1. RE2. RC2)

Note this is a degenerate model 

A* search for optimization, share 4-parameter (for bypassed model c_mu=3 pF, c_pi=22 pF) note: goal reached is actually current step, not current best

revised to OCT  model  A* search for optimization, share 4-parameter (for bypassed model c_mu=3 pF, c_pi=22 pF)

bypass model c_mu=2 pF, c_pi=12 pF (readme md)

revised (SA, 2N2222 added) c_mu=4 pF, c_pi calculated

OCT model (A*) c_mu=4 pF, c_pi calculated (share)
