Abstract

In this paper, a 1-volt 12-bit successive approximation analog-to-digital converter (ADC) has been proposed. The power dissipation is 50.9 uW with the sampling frequency of 40 KHz. Based on the simulation results, the used digital-to-analog converter with a calibration technique in ADC effectively reduces the differential nonlinearity. For biomedical applications, if the ADC input after the instrumentation amplifier is limited to 0.5 volt, the differential nonlinearity and the integral nonlinearity are within 1 LSB and 8.31 LSB respectively. The signal to noise ratio is 59.82 dB and the effective bit resolution is therefore 9.7 bits.
