Abstract
An integrated circuit (IC) device includes a controller circuitry having an input connected to a photodiode of an optoelectronic circuitry and an output connected to a biasing circuitry, the biasing circuitry having an input connected to the output of the controller circuitry, the controller circuitry configured to transmit a transimpedance control signal code to the biasing circuitry configured to cause the biasing circuitry to offset a DC current component of the output of the photodiode.
