Transistor BiasingBJT - Need for biasing-Fixed bias circuit, Load line and quiescent point. Variation of quiescent point due to h variation within manufacturers tolerance. Stability factors. Different types of biasing circuits. Method of stabilizing the Q point ot the extent possible. Advantage of self bias (voltage divider bias) over other types of biasing. Use of self bias circuit as a constant current circuit. Source self bias and voltage divider bias for FET. Use of JFET as a voltage variable resistor.Voltage doubler. 2. Voltage tripler 3. Voltage quadrapler Each circuit is further classified as, a. Half wave multiplier and b. Full wave multiplier. 8.12.1 Half Wave Voltage Doubler The Fig. 8.44 shows the circuit diagram of a half wave voltageanbsp;...
