Abstract
A successive approximation register analog-to-digital converter (SAR ADC) for high-speed applications. The SAR ADC uses at least one set of capacitors. Each set of capacitors is formed by 2capacitor cells. The set of 2capacitor cells is allocated into p capacitors C(p−1) to Cdecreasing in capacitance. C(p−1)<C(p−2)+C(p−3)+ . . . +C, and C(p−1) includes (2−2) capacitor cells.
