摘要:
A pipeline ADC implemented with both general charge redistribution stages and flip-around charge redistribution stages. Using the flip-around charge redistribution stages leads to reduced power/area consumption, but could lead to accumulation and propagation of errors. general charge redistribution stages are used to control/contain the errors. As a result, the ADC is implemented to achieve an acceptable bit error and power efficiency combination. According to another aspect of the present invention, the first stage is implemented as a flip-around charge redistribution stage (in combination with general charge redistribution stages in subsequent stages) since there is no accumulation of error from prior stages, and implementing the first stage as a flip-around charge redistribution stage gives maximum advantages in power efficiency.
