Abstract:
1. An optical signal receiver comprising: an optical signal detector configured to detect an optical signal and output a corresponding electrical signal; a transimpedance amplifier having only two amplifier stages which combined provide only one phase inversion, the transimpedance amplifier configured to receive and amplify the electrical signal to a level suitable for downstream processing, the transimpedance amplifier comprising: a first stage comprising one amplifier and a load, the first stage configured to receive a first stage input current and generate a first stage output voltage; a second stage forming a second stage output voltage such that the first stage input signal and the second stage output voltage have opposite voltage polarity and the second stage is a single stage based on phase delay contribution because it performs a voltage to voltage amplification, the second stage comprising: one or more receiver processing elements configured to process the amplified electrical signal received from the transimpedance amplifier.
