Use Tian's method instead of Middlebrook's? #25

Open hpretl opened 2 days ago

hpretl commented 2 days ago

Currently, the course uses Middlebrook's method for loop gain analysis. A slightly better method would be Tian's (M. Tian, V. Visvanathan, J. Hantgan, and K. Kundert, “Striving for small-signal stability,” IEEE Circuits Devices Mag., vol. 17, no. 1, pp. 31–41, 2001, doi: 10.1109/101.900125), so maybe change in a future revision.

Recently, I found an interesting paper on ten different simulation-based loop gain analysis methods: https://ieeexplore.ieee.org/abstract/document/6977998
