Q. Define Power-Supply Rejection Ratio?
An op amp's ability to disregard changes in power-supply voltage is measured by the power- supply rejection ratio (PSRR), which is specified by the change in offset voltage VOS for a 1-V change in dc power supply and is usually expressed in µV/V. A typical value is 15 µV/V.
Notations that are used in transistor circuits:- h ie = h 11e = Short circuit input impedance h 0e = h 22e = Open circuit output admittance
