Abstract :
An energy-efficient successive approximation register (SAR) analogue-to-digital converter (ADC) switching scheme is proposed for low-power biomedical applications. By dramatically reducing energy consumption in the first three bit-cycles, the average switching energy of the proposed scheme is reduced by 98.8% compared with the conventional architecture. The number of capacitors in the capacitor array of this proposed scheme is also reduced by 75.5% over the conventional approach.
