Abstract :
A successive approximation analog-to-digital converter (SA-ADC) for biomedical application is presented. It is based on 0.18-mum standard CMOS technology and operates at low supply voltage at 1 V. Boosted switch for sample-and-hold stage, split capacitor array for DAC, and clocked rail-to-rail comparator are used to achieve low-power consumption. The ADC has signal-to-noise-and-distortion ratio of 53 dB for supply voltage of 1 V, at sampling rate of 100 kS/s and power consumption of 8 muW.
