Abstract
A frequency converter includes a comparator, an error computation unit and a calibration unit. The comparator receives a reference voltage signal and a triangle wave signal, and outputs a switching signal. The switching signal is fed back to the error computation unit to calculate an error signal by computing the reference signal and the switching signal. The calibration unit calibrates the triangle wave signal or the reference voltage signal according to the error signal.
