Forney Factor Graph – 電路應用
所有 linear circuit (Kalman) 都會 preserve Gaussian message
a. small signal analysis
b. large signal but using other approximation technique
(i) extended Kalman (or extended factor graph model)
(ii) unscented Kalman (or unscented fator graph model)
(iii) MCMC approximation?
1. Noise analysis
2. Monte Carlo analysis of mismatch (Cadence DC mismatch?)
bandgap, DAC, reference?
3. Monte Carlo analysis of yield? (very difficult? depends on performance criterion)
