Abstract
An optical receiver circuit is disclosed, including a photodiode, an output terminal, a first amplifier stage, and an electrostatic discharge (ESD) protection circuit. The photodiode may generate a receiver current based on received optical signals. The first amplifier stage may be coupled between the photodiode and the output terminal and include a first inductor coupled between the photodiode and an input of a first inverter, and a second inductor coupled between the input of the first inverter and a first resistor. The first resistor may be coupled between the second inductor and an output of the first inverter. ESD protection circuit may be coupled to the input of the first inverter. The output terminal may generate an output signal based at least in part on the output of the first inverter.
