The term biasing refers to the electrical supply or the potential difference associated with a semiconductor diode. The two primary types of bias include forward bias and reverse bias. Forward bias involves a reduction in the potential barrier of the semiconductor diode and it also involves the establishment of an easy path for the flow of current. On the other hand, reverse bias involves an increase in the strength of the potential barrier, which results in the prevention of the movement of the charge carrier across the junction diode. It is important to note that reverse bias generally provides a highly resistive path for the current to flow and is generally accompanied by no current flowing through the circuit.
