Emitter bias:
Figure: Emitter bias
While a split supply (dual power supply) is accessible, this biasing circuit is the very much effective, and gives zero bias voltage at the emitter or collector for load. The negative supply VEE is employed to forward-bias the emitter junction by RE. The positive supply VCC is employed to reverse-bias the collector junction. Just only two resistors are essential for the common collector stage and 4 resistors for the common emitter or common base stage.
We know that,
VB - VE = Vbe
If RB is sufficiently small, base voltage will be almost zero. Hence emitter current is,
IE = (VEE - Vbe)/RE
The operating point is independent of β if RE >> RB/β
Merit:
Good stability of operating point identical to voltage divider bias.
Demerit:
This type can just only be used while a split (dual) power supply is available.
Develop and execute a program to analyze the circuit shown in Figure (a), and use PROBE for plotting v C (t).
What is the use of 8251 chip? 8251 chip is mostly used as the asynchronous serial interface among the processor and the external equipment.
Q. Determine v o /v i for the circuit shown in Figure if the op amps are ideal.
