Abstract: In one example embodiment, a transmitter module includes a header electrically coupled to a chassis ground. First and second input nodes are configured to receive a differential data signal. A buffer stage has a first node coupled to the first input node and a second node coupled to the second input node. An amplifier stage has a fifth node coupled to a third node of the buffer stage and a sixth node coupled to a signal ground that is not coupled to the chassis ground. An optical transmitter has an eighth node coupled to a seventh node of the amplifier stage and a ninth node configured to be coupled to a voltage source. A bias circuit is configured to couple a fourth node of the buffer stage to a bias current source.

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.

Abstract: An integrated circuit may include a signal generator configured to generate a switching signal and a switching unit coupled to the signal generator. The switching unit may be configured to generate a pulsed current based on the switching signal using a first voltage. The integrated circuit may also include an inductive unit coupled to the switching unit. The inductive unit may be configured to receive the pulsed current and to generate a second voltage different from the first voltage.
