ABSTRACT:
An amplifying circuit receives an output from a comparator. The output is provided to each gate of first, second and third transistors. First and second resistors are connected in series. The first and second resistors and a first diode are connected to a drain of the first transistor. Second diodes are connected in parallel. The second diodes are connected to one end of a third resistor. The other end of the third resistor is connected to a drain of the second transistor. Fourth and fifth resistors are connected in series. One end of the fourth resistor is connected to the drain of the second transistor. The comparator receives first and second feedback voltages respectively obtained from a connection node between the first and second resistors and a connection node between the fourth and fifth resistors. A drain of the third transistor outputs a reference voltage.
