![]() By selecting the proper resistor values, stable current levels can be achieved that vary only little over temperature and with transistor properties such as.The of a device, also known as bias point, quiescent point, or Q-point, is the point on the output characteristics that shows the collector–emitter voltage ( V ce) and the collector current ( I c) with no input signal applied. The voltage divider configuration achieves the correct voltages by the use of resistors in certain patterns. Much more elaborate biasing arrangements are used in, for example. In circuits made with individual devices (discrete circuits), biasing networks consisting of are commonly employed. A diagram, illustrating an operating point in the transistor's active regionmust be properly to operate correctly.
