—In this paper, we present a fully integrated front-end of a portable spectroreflectometry-based brain imaging system dedicated for acquisition of modulated optical signals at a frequency of 1 Hz to 25 kHz. The proposed front-end preamplifier is composed of a photodetector, a transimpedance preamplifier, a two-stage voltage amplifier and a mixer. Strict(More)
A flexible digital intellectual property (IP) module that controls the auto-calibration of time interleaved pipelined ADCs is presented. It takes advantage of a judicious combination of classical calibration techniques to determine, in an adaptive way, the adequate compensation of gain and offset for each stage of interleaved pipelined ADCs.
