Abstract

In this paper, we discuss the low power design of a 1-volt 12-bit analog to digital converter (ADC) for biomedical signal applications. We use both the fixed reference voltage, and the complementary signal generator for the design of the mixed charge serial DAC. It is effective to improve the DAC characteristics. The obtained DNL is +0.08LSB -0.08LSB and INL 0.043 -0.065LSB respectively. Besides, an offset cancellation and sleep control are designed for the comparator circuit to reduce mismatching error and save power.
