Abstract :
A two-stage pipelined ADC employs a double-sampling residue amplifier, two interleaved precharged DACs, and a new calibration scheme to correct for residue gain error, offset, and nonlinearity. Realized in 65-nm CMOS technology and sampling at 1 GHz, the prototype exhibits an FOM of 25 fJ/conversion-step while drawing 7.1 mW from a 1-V supply.
