Abstract
Supporting advanced modulation schemes such
as 16 quadrature-amplitude modulation (QAM) in a high-
speed transimpedance amplifier (TIA) requires minimizing noise
and total harmonic distortion (THD) across gain settings and
frequency. Accordingly, our automatically reconfigurable TIA
reduces base resistor noise, gain peaking, phase margin (PM)
degradation, and fT degradation, operating on a single sense
voltage and eliminating the need for multiple control loops.
