摘要：This paper presents the high speed and high resolution analog to digital conversion using successiveapproximation registers (SAR) with split DAC structure based on combining three ADC architectures namely splittype SAR, Sigma-Delta and flash type ADC using pipelining method. The static linearity performance of thisapproach is based on integrating parallelism and pipelining method in SAR with reconfigurable sampling rate tomaintain the tradeoff between speed, accuracy, resolution and architectural complexity. Gaussian smoothing functionis introduced to improve the linearity and to remove glitches. This architecture flexibility provides higher resolutionand high speed Performance is demonstrated and verified by behavioral simulations using Modelsim 6.4a.Measurement results of power, speed, and linearity of this approach are measured through Quartus II 9.0 IDE thatclearly shows the benefits of hybrid SAR ADC in terms of area complexity and speed.
