Abstract
A diode control device include a first terminal for receiving a first power supply voltage and a second terminal for receiving a second power supply voltage. A circuit of the diode control device applies a regulated voltage on the anode of the diode in response to a control voltage. The control voltage is equal to a preset voltage when a reference voltage is less than or equal to zero. Conversely, when the reference voltage is greater than zero, the control voltage is equal to the sum of the present voltage and a difference between cathode voltage of the diode and the reference voltage.
