摘要
Methods and systems to amplify and convert a single-ended analog signal to a differential signal and to convert the differential signal to a digital value, including to time-multiplex a plurality of windowed single-ended analog error signals, amplify a difference between the time-multiplexed analog signals, sample a corresponding amplified difference signal and an inverted amplified difference signal, amplify and center the samples about a common mode, and convert a corresponding amplified differential signal to digital values in a pipeline fashion. Bias adjustable features may be implemented to control a bandwidth, and clock rates may be adjustable to correspond to the bandwidth.
