<P> For bipolar junction transistors the bias point is chosen to keep the transistor operating in the active mode , using a variety of circuit techniques , establishing the Q - point DC voltage and current . A small signal is then applied on top of the Q - point bias voltage , thereby either modulating or switching the current , depending on the purpose of the circuit . </P>
