Lesson 1

Design a Two-Stage BJT Amplifier (Parameters to optimizeRE1, 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)

using 2N2222 parameters (share)
