A circuit for calibrating a voltage signal. The circuit includes a first voltage-to-current converter receiving the signal to be calibrated and a reference voltage, and providing a current proportional to the voltage difference between the voltage of the signal to be calibrated and the reference voltage, a first current amplifier driven by the first voltage-to-current converter, a second voltage-to-current converter receiving an adjustment voltage and the reference voltage and providing a current proportional to the voltage difference between the adjustment voltage and the reference voltage, a second current amplifier driven by the second voltage-to-current converter, and a means for providing a calibrated voltage signal based on the difference between the currents provided by the first and second current amplifiers.
