To prove the concept, the circuit is implemented in a 22 nm fully-depleted silicon-on-insulator (FDSOI) technology. Key power dissipating factors are explored considering the high sampling rate. A scheme is investigated, where each memory cell activates the second next memory cell to relax the speed requirement and allow for power savings compared to conventional approaches. A modified, non-overlapped signaling is used in the driver for the capacitive digital-to-analog converter (CDAC) to reduce a direct-path current and to ease the reference buffer design. Measurements show an effective number of bits (ENOB) of 6.86 bit near the Nyquist frequency.
