Abstract
In one example, a device includes a photodetector to generate an electrical signal in response to an optical signal and a transimpedance amplifier unit to receive the electrical signal. In one example, the transimpedance amplifier unit may include a first inverter unit, a second inverter unit coupled to the first inverter unit, and a third inverter unit coupled to the second inverter unit. In one example the third inverter unit may include a feedback resistor and a first n-type transistor in parallel to the feedback resistor, where the first n-type transistor is to provide a variable gain of the third inverter unit.
