Physics · Transistor Biasing
Consider a fixed-bias circuit using an NPN BJT in a Common Emitter (CE) configuration with base resistance Rb, collector resistance Rc, and supply voltage VCC. If β represents the common-emitter current gain, then the stability factor (S) of this fixed-bias circuit with respect to leakage current is:
