Patent ID: 8509629

Claim:
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 amplifier configured to receive and amplify the first stage output voltage and generate a second stage amplifier output current; a voltage conversion device configured to receive and convert the second stage amplifier output current to the second stage output voltage, the second stage output voltage inverted in relation to the second stage amplifier output current; a feedback path including a feedback resistor, the feedback path connecting an output of the second stage to an input of the first stage to provide negative feedback as a result of the opposite voltage polarity; one or more receiver processing elements configured to process the amplified electrical signal received from the transimpedance amplifier.
