Abstract
A current sensor automatically adjusting an offset voltage, includes an input corrector, upon receiving a first voltage, a second voltage, and a control signal, configured to correct either one or both of the first voltage and the second voltage to reduce an absolute value of a difference between the first voltage and the second voltage based on the control signal, and output a correction result; an input amplifier configured to amplify a voltage output from the input corrector; an output amplifier configured to generate an output voltage when a voltage amplified by the input amplifier is input; a controller including a switch connected to one of voltages amplified by the input amplifier to be grounded when a difference between the first voltage and the second voltage is larger than a first threshold value; and a correction circuit controller configured to generate the control signal to input to the input corrector.
