Biasing: Biasing in electronics is the method of establishing predetermined voltages and/or currents at various points of an electronic circuit to set an appropriate operating point. The operating point of a device, also known as bias point, quiescent point, or simply Q-point, is the point on the output characteristics that shows the direct current (DC), collector-emitter voltage (V CE ), and the collector current (I C ) with no input signal applied. The term is normally used in connection with devices such as transistors. Collector Feedback Bias: This configuration employs negative feedback to prevent thermal runaway and stabilize the operating point. In this form of biasing, the base resistor RB is connected to the collector instead of connecting it to the DC source Vcc. So any thermal runaway will induce a voltage drop across the RC resistor that will throttle
