Bipolar transistor biasing

Biasing is the setting of the DC operating point of an electronic component. For bipolar junction transistors (BJTs), the operating point is defined as the steady-state DC collector-emitter voltage ( V c e {\displaystyle V_{\mathrm {ce} }} ) and the collector current ( I c {\displaystyle I_{\mathrm {c} }} ) with no input signal applied.
