Common issues in BJT diff pair design
(by TA)
1. unfinished routing
2. one stage diff pair 是沒有 miller 電容 cc
(by TA)
1. SA 是無效的
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
Poly R: 250 Ω/sq (±20%)
MIM C: 1 fF/μm² (±15%)

HW#6 A* Circuit Optimization
課堂練習
Deadline: This Saturday at 23:59
Send all the share links to me chang212@gmail.com by email with subject HW#6 ［your id, your name]
任選一題
1. Design a Two-Stage BJT Amplifier according to goals specified using A* (Parameters to optimize RE1, RC1. RE2. RC2)
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
