Bias is used in a variety of ways, but in electronic circuits, bias refers to the application of a DC voltage or current to an AC circuit. In Matsusada Precision's bipolar power supplies and high-voltage amplifiers, we offer models with a bias function so that the bias can be set according to the specimen to which the voltage is applied.

In diodes, the words forward bias and reverse bias also exist. Forward bias refers to connecting a positive power source to a P-type semiconductor and a negative power source to an N-type semiconductor. Light emitting diodes are this connection.

Reverse bias refers to connecting a negative power supply to the P-type semiconductor and a positive power supply to the N-type semiconductor. When a power supply is connected to a photodiode, this reverse bias connection is used. By connecting in the reverse direction, current flows only when light is incident and light can be detected.
