1. The problem statement, all variables and given/known data I have this schematic for a clapp oscillator (see "ClappwBias") which includes the DC biasing network. When broken up into feedback topology, I end up with something like "betanet", where the output is taken from the source of the MOSFET. 2. Relevant equations If so, then B=If/I0. 3. The attempt at a solution Am I correctly seeing this as a shunt-series topology? The only thing that makes me doubt it is if what matters is where the load is taken from. I'm assuming series connection at the output of the transistor because the Drain is grounded, but considering the load, the output voltage (of the transistor) is in shunt with the load.
