Abstract :
A new architecture is proposed which reduces the power consumption and capacitor area in successive approximation register (SAR) analogue-to-digital converters (ADCs). Two identical capacitor-splitting capacitor arrays are used in a two-step process for quantisation, and this significantly reduces the switching power and capacitor area.
