<p>A first order error feedback based noise shaping in a double sampled ADC is proposed. This topology is ideal for nanometer CMOS technology, as it obviates the need for high-gain and high output-swing op amps and fast-settling, power-hungry, and noisy reference buffers. Using a one stage op amp with a gain of 70 (i.e. 37 dB) and output swing of ±75 mV , this topology, realized in GPDK 90-nm CMOS technology, achieves an SNDR of 60 dB operating at 1 GHz (effective sample rate of 2 GHz due to double sampling) with an OSR of 32. © 2012 IEEE.</p>
