  • Integrated power supply for fiber optic communication devices and subsystems
    Patent number: 9941864
    Abstract: An example embodiment includes a fiber optic integrated circuit (IC). The fiber optic IC includes an integrated power supply. The integrated power supply includes a filter, an active switch, and a pulse width modulator (“PWM”). The filter is configured to convert a signal to an output signal of the integrated power supply. The active switch is configured to control introduction of the signal to the filter. The PWM is configured to generate a PWM output signal that triggers the active switch.
    Type: Grant
