Abstract
A power detector includes a first current mirror that receives an input signal and generates a mirrored input signal, a first oscillator that reverses a first current of the mirrored input signal based on a voltage of the mirrored input signal reaching a threshold, and a first counter that generates a first count of each period generated by the first oscillator. The power detector also includes a second current mirror that receives a reference signal and generates a mirrored reference signal, a second oscillator that reverses a second current of the mirrored reference signal based on a voltage of the mirrored reference signal reaching the threshold, and a second counter that generates a second count of each period generated by the second oscillator. A processor then determine the power of the input signal based on the first count and the second count.
