Transistors - Bipolar (BJT) - Single, Pre-Biased
Pre-biased bipolar transistors have internal resistors designed to maintain the device near the bias or operating point with no input signal applied. Transistor biasing allows the transistor to work more efficiently and produce a stable, undistorted output signal. Pre-biased transistors reduce the number of external circuit components required, thereby reducing project costs.
