Abstract
A differential transimpedance amplifier (DTIA) includes a first input, a second input, a first output, and a second output. The DTIA also includes a first inverter and a second inverter connected in series to the first input. The DTIA further includes a third inverter and a fourth inverter connected in series to the second input. The first inverter and the fourth inverter receive a first supply voltage from a first voltage regulator. The second inverter and the third inverter receive a second supply voltage from a second voltage regulator. The first supply voltage changes (i) based on a difference between voltages on the first output and the second output and (ii) while the second supply voltage remains fixed.
