What is Bias Voltage?

The bias voltage is the amount of voltage that an electronic device needs in order to power on and function. Bias voltage must be carefully chosen to operate the device, meaning the power to operate the device must be at a specific level. With too little bias voltage, the power that is sent to the device may be insufficient to turn it on and, thus, the device will not power on. With too much bias voltage, the device may receive too much current and can be destroyed. Check with the manufacturer of the device in use to check how much bias voltage it should receive.
