Signal swing of amplifiers
WebThe goal in amplifier stability analysis is two-fold: Determine whether a given amplifier design is stable. If an amplifier is unstable, determine what causes the instability. If you … WebMar 4, 2010 · Now the maximum swing we can take is 1.12mA or base swing as 6.25uA. The maximum base current would correspond to maximum base voltage. So maximum base current is 14.69uA+ 6.25uA = 20.925uA We are now adding a AC source for this additional base current that the design can faithfully amplify. Let this voltage be Vext.
