Integrated circuits in optical receivers

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.

1. A circuit comprising:
a photodiode configured to receive an optical signal and convert the optical signal to a current signal; a transimpedance amplifier configured to convert the current signal to a voltage signal; an equalizer configured to equalize the voltage signal to at least partially compensate for a loss of a high frequency component of the optical signal; and a driver coupled to the equalizer, the driver comprising a non-linear driver configured to drive the equalized voltage signal to a clock and data recovery circuit in a first integrated circuit separate from a second integrated circuit that includes the driver, the equalizer, and the transimpedance amplifier.
