Web4/25/2011 MOSFET Biasing using a Single Power Supply 2/9 Ag vo m∝ Thus, to maximize the amplifier voltage gain, we must maximize the MOSFET transconductance. Q: What does this have to do with D.C. biasing? A: Recall that the transconductance depends on the DC excess gate voltage: g mGSt=2KV V(−) WebBiasing circuits for depletion type MOSFET are quite similar to the circuits used for JFET biasing. The primary difference between the two is the fact that depletion type MOSFETs …

WebThe self-biased source has no external biasing network. The self-biased circuit is simpler than the external bias circuit because it does not need a negative bias power supply, and is thus completely independent of variations in such bias supply voltages. Consequently, the circuit can be powered by a wide range of supply voltages.
