  • High efficiency pulse width modulator
    Patent number: 5910743
    Abstract: The apparatus and the method representing an improved power management system are disclosed. The apparatus incudes a feedback control system with a delay element. The delay element introduces the oscillation frequency outside the input frequency band into the feedback control system. Therefore, the apparatus emulates a very efficient pulse width modulator (PWM) with a feedback. The apparatus additionally includes a pulse shaper amplifier that squares the pulse of the output signal.
