What is the DC gain of two op amps?
The two op-amps are designed to have a DC gain of about 70 dB and 60 degrees of phase margin. The indirect feedback compensation design showed similar simulation results as the Miller compensation technique; nevertheless, it showed a reduce in the compensation capacitor size, meaning a smaller design
Where does the minus sign in MOSFET come from?
This minus sign comes from the fact that the I D current is flowing from GND into drain terminal in our small signal equivalent circuit. In reality this minus sign only inform us that our amplifier output voltage is 180° out of phase with respect to the input voltage.
How to find the gain in MOSFET circuit?
From this you choose a Source Follower design (unity gain) or Common Source design with drain load or Drain/ (Rsource+RdsOn) impedance ratio for small signal ratio gain. Thanks for contributing an answer to Electrical Engineering Stack Exchange!
Why is the Overdrive voltage of a MOSFET important?
By increasing V OV, I D can be increased until saturation is reached. Overdrive voltage is also important because of its relationship to V DS, the drain voltage relative to the source, which can be used to determine the region of operation of the MOSFET.
