Abstract
A pulse width modulating (PWM) circuit includes an activating module and a pulse generating module connected to the activating module. The activating module includes a current resource and a compensation unit. The current source generates an activating current, and the compensating unit detects the activating current and compensates the activating current if the activating current changes. The activating current is input to the pulse generating module to generate pulse voltages output by the pulse generating module.
