Abstract:
In at least some examples, a communication device includes a photo-diode to convert an optical signal into an electrical current and a feedback-based trans-impedance amplifier to amplify the electrical current. The communication device also includes a transmission line between the photo-diode and the feedback-based trans-impedance amplifier. The feedback-based trans-impedance amplifier includes a programmable input impedance that has been matched to an impedance of the transmission line.
