Abstract
This case proposes a high-resolution pipelined ADC based on multiple-phase capacitor-splitting feedback interchange methodology. This methodology can compensate the capacitor-mismatch errors caused by process variation in each pipelined stage, then boost the ADC linearity and resolution. The operational principle of the methodology is to choose different capacitors as feedback ones according to different pipelined stages, phases and sub-analog-to-digital converter codes. When designing ADCs, we can design smaller capacitors and reduce the design difficulty of the operational amplifiers (OP) in the ADC by using the proposed methodology, then gain the speed of the ADC and reduce the power consumption and chip area. Even the ADC's resolution is higher, the design difficulty of the OP will not increase much. The representative picture of the case is Figure 700, which contains sample-and-hold amplifier 701, pipelined stages 702, sub-analog-to-digital converter in each pipelined stage 703, multiplying digital-to-analog converter in each pipelined stage 704, control logic in each pipelined stage 705, synchronous circuit 706, digital error correction circuit 707, clock generator 708, bandgap voltage reference 709 and the digital outputs 710.
