SUMMARY

The discussion centers on verifying the small-signal gain of a MOSFET circuit, specifically addressing the absence of JFETs and the exclusion of body effect. Participants question the definitions of parameters r01, r02, and r03, suggesting they refer to channel resistance. Additionally, there is confusion regarding the notation "||" and the relationship between gm2 and GM3, indicating a need for clarity in the circuit's small-signal model.

It is a bit difficult to tell without relevant equations.
The sign is probably correct.

What are r01, r02, r03 ? Channel resistance?
What does || mean in your shorthand?
Where is gm2. Is it = GM3 ?
