Abstract

In this paper, a novel one bit resolution ADC for wireless communication devices is presented. If we use a conventional one bit resolution ADC for wireless communication devices, the communication quality becomes worse due to heavy non-linearity. To overcome this problem, we proposed a novel one bit resolution ADC circuit with linearity enhancement technique, which uses a S/H and a hysteresis comparator. By using hysteresis effect, the periodicity of one bit resolution ADC output signal can be reduced. Signal-to-Quantization-Noise Ratio (SQNR) can be improved by 6.4dB, thanks to the proposed technique.
