CPC H02M 3/1582 (2013.01) [G05F 1/62 (2013.01)] | 20 Claims |
1. An integrated circuit device, comprising:
an input stage configured to receive a first input signal and a second input signal and generate a first voltage based on the first input signal and generate a second voltage based on the second input signal;
an amplification stage configured to generate a first output current based on the first voltage and generate a second output current based on the second voltage;
a bias stage configured to generate a bias voltage for the amplification stage based on the first voltage and the second voltage;
a load stage configured to output a differential voltage signal based on a comparison of the first output current and the second output current, wherein the differential voltage signal is proportional to a current through a device for which current is sensed; and
an output stage configured to output a signal to control a duty cycle of the device for which current is sensed based on the differential voltage signal generated by the load stage.
