1. An adaptive receiver, comprising:
a current buffer;
an inverter-based transimpedance that receives input from the current buffer;
an average current control loop that feeds back from the inverter-based transimpedance to the current buffer;
a variable gain circuit that receives input from the inverter-based transimpedance;
a differential voltage amplifier that receives input from the variable gain circuit;
an automatic gain control loop that feeds back from the differential voltage amplifier to the inverter-based transimpedance and variable gain circuit; and
a differential buffer that receives input from the differential voltage amplifier.
