摘要： A circuit may include an input node configured to receive a signal and an output node configured to be coupled to a load. The circuit may also include a first circuit coupled between the input node and the output node. The first circuit may be configured to receive the signal and to drive the signal on the output node at a first voltage. The circuit may also include an active device coupled to the output node and a second circuit coupled to the active device and the input node. The second circuit may be configured to receive the signal and to drive the signal to the active device at a second voltage. The circuit may also include a tap circuit configured to selectively apply a modified version of the signal to the signal driven by the second circuit before the signal driven by the second circuit reaches the active device.

摘要： A circuit may include a photodiode configured to receive an optical signal and convert the optical signal to a current signal. The circuit may also include a transimpedance amplifier coupled to the photodiode and configured to convert the current signal to a voltage signal. The circuit may also include an equalizer coupled to the transimpedance amplifier and configured to equalize the voltage signal to at least partially compensate for a loss of a high frequency component of the optical signal. The equalizer and the transimpedance amplifier may be housed within a single integrated circuit.

摘要： In an example embodiment, a phase-locked loop circuit may include a first circuitry to receive a reference signal and a source signal. The first circuitry may generate a correction signal for demonstrating a difference in phase between the reference signal and the source signal. The phase-locked loop may include a second circuitry to receive the correction signal. The second circuitry may generate a digital signal for demonstrating a phase-to-digital conversion of the correction signal. The phase-locked loop may include a third circuitry to receive the digital signal. The third circuitry may generate a control signal for demonstrating a converted voltage of the digital signal. The phase-locked loop may include a fourth circuitry to receive the control signal. The fourth circuitry may generate the source signal in response to the control signal.

摘要： In one example embodiment, an optoelectronic module includes an optical receiver and a post-amplifier. The optical receiver is configured to receive an optical signal and generate an electrical data signal corresponding to the optical signal. The post-amplifier is electrically connected to the optical receiver and is configured to amplify the electrical data signal. The optoelectronic module further includes means for quantifying a quality of the optical signal from which the amplified electrical data signal is derived.
