This article reports a power-efficient 8× time-interleaved (TI) 2.4-GS/s 10-bit successive-approximation-register (SAR) analog-to-digital converter (ADC). To optimize the circuit design in terms of power efficiency and conversion rate, several enhancement techniques are presented. First, a pre-defined bypass window, introduced by the customized non-binary DAC, is used to modestly reduce the
