WebThe input circuit of BJT is forward biased. Hence BJT has low input impedance. FET is a voltage driven device. BJT is a current operated device. In BJT the output current is controlled by the variations in the input current. It produces a current gain. But in a FET, a small voltage at its gate controls the drain current. Thus FET produces a ... WebJun 21, 2024 · Summary: 1. BJT is a Bipolar Junction Transistor, while MOSFET is a Metal Oxide Semiconductor Field-Effect Transistor. 2. A BJT has an emitter, collector and base, while a MOSFET has a gate, source and drain. 3. BJTs are preferred for low current applications, while MOSFETs are for high power functions. 4.

In a linear regulator, switching speed isn't a consideration. However, BJT base current can be. There's no steady-state gate current in a MOSFET so a MOSFET can be lower loss. Also, a MOSFET in the on state looks resistive, so the dropout voltage can be very small at low currents. A BJT will saturate and may lead to higher dropout voltage at ...
