WebBelow is a typical BJT receiving voltage divider bias: For the circuit above, we're going to assume that β=100 for the transistor. The base supply voltage, V BB, is calculated by: We calculate R B below, which we will use the next calculation for I E. Then, we calculate for the emitter current using the following formula: http://www.ittc.ku.edu/~jstiles/312/handouts/section%205_4%20BJT%20Circuits%20at%20DC%20package.pdf 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. camping in cold weather tips
