Abstract
A reduced power consumption diode circuit has a first voltage comparator that compares a voltage at a cathode terminal with a first sum of a voltage at an anode terminal and a voltage across a second voltage source, and outputs a reset signal. A second voltage comparator compares the voltage at the anode terminal with a second sum of the voltage at the cathode terminal and a voltage across the first voltage source, and outputs a set signal. A first latch circuit outputs a low level signal when the reset signal is input and a high level signal when the set signal is input. A diode has an anode connected to the anode terminal and a cathode connected to the cathode terminal, and an n-channel MOS transistor turns off in response to the low level signal and turns on in response to the high level signal.
