ABSTRACT:
A method for achieving high-speed analog-to-digital conversion without degrading accuracy includes: receiving digital outputs of a plurality of pipelined analog-to-digital converters (ADCs) that perform analog-to-digital conversion on a same analog signal; and performing digital calculations on the digital outputs to generate a calibrated digital output. An apparatus for achieving high-speed analog-to-digital conversion without degrading accuracy is further provided. The apparatus includes: a digital module arranged to receive digital outputs of a plurality of pipelined ADCs that perform analog-to-digital conversion on a same analog signal. In addition, the digital module includes a plurality of digital calculation paths respectively corresponding to the pipelined ADCs, wherein each digital calculation path corresponding to an associate pipelined ADC of the pipelined ADCs is electrically connected to the associate pipelined ADC. The digital module performs digital calculations on the digital outputs to generate a calibrated digital output.
