Abstract

A circuit for use with PWM signal having first pulse and a second pulse, wherein the first pulse has a period and a first duty cycle, and the second pulse has the period and a second duty cycle. The period has clock information therein, the first duty cycle has first data information therein, and the second duty cycle has second data information therein. The circuit includes a first integrating component and a second integrating component. The first integrating component can generate a first voltage corresponding to the first duty cycle and a second voltage corresponding to the first duty cycle. The second integrating component can generate a third voltage corresponding to the second duty cycle and a fourth voltage corresponding to the second duty cycle.
