Abstract
A calibration circuit for calibrating a device to be calibrated includes a variable current generator, a circuit component, and a control unit. The variable current generator generates a variable current responsive to variations of a supply voltage relative to a predetermined voltage level. The circuit component is a copy of at least one portion of the device to be calibrated and is coupled between the variable current generator and the supply voltage. The control unit is coupled to the variable current generator and the circuit component, and generates, based on a voltage dependent on the variable current and the circuit component, at least one calibration signal for adjusting an adjustable electrical parameter of the circuit component and the device to be calibrated.
