CPC G05F 1/56 (2013.01) [H03K 17/08 (2013.01)] | 8 Claims |
1. A mirror clamp circuit comprising:
a comparator having:
a first input terminal connectable to a first control terminal of a transistor having
the first control terminal connected to another terminal of a resistor of which one terminal is fed with an output voltage and
a first terminal fed with a reference potential; and
a second input terminal fed with a reference voltage;
a transistor switch having a second control terminal fed with a control terminal voltage based on a comparison signal output from the comparator, the transistor switch being inserted between the first control terminal and the reference potential;
an OR circuit fed with a signal based on the control terminal voltage and the output voltage; and
a current feeder configured to change an amount of current fed to the comparator based on an output of the OR circuit.
