Abstract

A power detection circuit is provided for detecting current total input power of a resonant circuit. The power detection circuit includes a detection circuit and an estimation circuit. The detection circuit receives a current signal and obtains resonant-slot baseband power according to the current signal to generate the baseband power value. The current signal represents a resonant-slot current generated by the resonant circuit. The estimation circuit receives the baseband power value and estimates the current total input power according to the baseband power value to generate an estimated power value.
