Common issues in BJT diff pair

BJT diff pair

Routing

(by TA)

1. unfinished routing

2. one stage diff pair 是沒有 miller 電容 cc

miller 電容在 stage 2 

Parameter Optimization

 (by TA)

1. SA 是無效的    

檢查sa 效能 

2. 檢查是否合規 

gain 47.6 db 不夠

PM 0 很危險，不穩定

GBW 太大

設計目標 (3.3V):

Ad ≥ 50 dB  |  CMRR ≥ 80 dB

GBW ≥ 100 MHz  |  PM 55°–75°

Vos ≤ 1 mV  |  Pd ≤ 20 mW

任選一題

1. Design a Two-Stage BJT Amplifier according to goals specified using A* (Parameters to optimize RE1, RC1. RE2. RC2) 

A* search for optimization, share  (c_mu=3 pF, c_pi=22 pF)

2. Optimize LM3886 class AB audio amplifier IC using A* (Parameters to optimize: resistors except the load) 

LM3886

A Search Setup*

• State space: 5 components × 5 E12 values each = 3,125 possible states
• g(n): actual steps taken from the start configuration
• h(n): circuit performance cost (the heuristic) — sum of 5 weighted penalties
• f(n) = g + h: A* priority queue ordering

Cost function (5 components, all minimized):

• Gain: quadratic penalty for deviation from 26 dB (20×)
• f_low: penalty if low-frequency cutoff exceeds 10 Hz
• f_high: penalty if high-frequency cutoff falls below 100 kHz
• Bias: penalizes Rb1 ≠ Rb2 (asymmetric thermal tracking)
• Re stability: log-scale penalty away from 0.47 Ω optimum

Weight/ Forms

Are Re1 and Re2 Always Equal?

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
