Abstract
A circuit includes a compensation inductor, a compensation resistor, and a current emulation circuit. The current emulation circuit has a time constant smaller than a time constant of the compensation inductor and the compensation resistor. The current emulation circuit includes a sense resistor having a first terminal coupled with a first terminal of the compensation inductor, and a sense capacitor having a first terminal coupled with a second terminal of the sense resistor and a second terminal coupled with ground.
