Bjt as a switch simulation

WebCircuit Description. This circuit demonstrates how to improve the switching speed of BJTs using a speed-up capacitor. Both the turn-on and turn-off times of the BJT are reduced. The speed-up capacitor works as follows: When the input is at low state and the capacitor is fully discharged, the voltage across its plates is 0 V.

WebThe BJT is "cutoff" because IC is essentially zero and all of VCC appears across the transistor collector-emitter terminals. The BJT is "saturated" if IC reaches its maximum value along the load line (IB > 100 μA). Therefore, the transistor can be operated as an OFF switch with IB = 0 μA and as an ON switch with IB = 100 μA. WebApr 9, 2024 · BJT definition and characteristics. BJT transistor is a three terminal semiconductor device, based on three layers of p and n layers, with different doping concentration. BJT transistor can be two types – pnp and npn BJT transistor.
