Providing large currents as the voltage gets to extreme values is difficult for MOSFET circuits to accomplish. • If one considers the MOSFET driver, the emitter can only pull to within vBE+VON of the power supply rails. This value can be 1V or more. WebMay 22, 2024 · The key characteristics of a voltage follower are a high input impedance, a low output impedance and a non-inverting voltage gain of approximately one. The name comes from the fact that output voltage follows the input, that is, it's at the same voltage level and is in phase with the input. dean mercer death
