Abstract

A new self-timed timing control and WRV (Without Reference Voltage) algorithm based on the conventional SA-ADC architecture to detect biomedical signals is proposed in this paper. Using the new self-timed control method, the conversion time could be shortened to turn off the analog circuit earlier to lower the power consumption. In addition, a new WRV algorithm is introduced to remove the circuits of reference voltage sources in the DAC sub-circuit inside the SA-ADC. By this way, both INL and DNL errors of this SA-ADC are well controlled in 0.33LSB from simulation results. Also, the input range of this proposed SA-ADC can be extended to rail-to-rail.
