Abstract
A voltage regulator which includes a differential amplifier circuit containing a first and second input transistors, controlling a gate-source voltage in each of the first and second input transistors including: a current source configured to drive the differential amplifier circuit; the first input transistor containing a gate; the second input transistor containing a gate; and a voltage controller including at least one of a first voltage control circuit to control a voltage at a tail connection point, a second voltage control circuit to control the voltage at the gate of the first input transistor, a third voltage control circuit to control the voltage at the tail connection point, and a fourth voltage control circuit to control the voltage at the gate of the second input transistor.
