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