Abstract
A semiconductor circuit includes a differential amplifier having a first positive terminal, a second positive terminal, a first negative terminal, a second negative terminal, and an output terminal. The output voltage is at a level that corresponds to a voltage level obtained by subtracting a voltage of the first negative terminal and the second negative terminal from a voltage sum of the first positive terminal and the second positive terminal. A first diode has a first anode connected to one of the first positive or the first negative terminal. A second diode has a second anode connected to the other of the first negative and first positive terminal. A predetermined reference voltage is applied to the second positive terminal. And a voltage corresponding to the output voltage of the differential amplifier is fed back to the second negative terminal.
