Claim 0:
1. A method of for full cycle error correction of inductor current measurement for switching regulators, the method comprising:
generating a ramp down compensation voltage based at least partially on a valley current sense voltage and an inductor voltage of an inductor at an inductor node;
applying the ramp down compensation voltage to the inductor node;
in response to a first determination that the valley current sense voltage and the inductor voltage are not equal, applying a control signal to a system capacitor; and
in response to the applying the control signal, modifying to a first modified capacitance a predetermined capacitance of the system capacitor, the system capacitor operatively coupled at a first terminal to the inductor node and at a second terminal to a reference voltage.
