Abstract
A power stage circuit includes a switch circuit, a driving circuit and a current monitoring circuit. The driving circuit drives the switch circuit according to a control signal to generate an output current signal. The current monitoring circuit includes a current sensing circuit, a virtual current signal generation circuit and a signal combination circuit. The current sensing circuit senses the output current signal to generate a low-side current signal. The virtual current signal generation circuit generates a low-side voltage signal according to the low-side current signal, generates and adjusts a digital signal according to a comparison result of the low-side voltage signal and a virtual voltage signal, adjusts the virtual voltage signal according to the digital signal, and generates a virtual current signal according to the virtual voltage signal. The signal combination circuit generates a current monitoring signal according to the low-side current signal and the virtual current signal.
