摘要:
A pipelined ADC includes a first, second, and third pairs of comparators. The first pair of comparators compare an input voltage to a first positive reference voltage and to a first negative reference voltage. The second pair of comparators compare the input voltage to a second positive reference voltage and to a second negative reference voltage. Each comparator of the first and second pairs of comparators outputs a digital signal to an encoder. A third pair of comparators compares the input voltage to a third positive reference voltage and to a third negative reference voltage, and a comparator compares the input voltage to ground. The comparator and each comparator of the third pair of comparators is configured to output respective digital signals to an encoder. A multiplying digital-to-analog converter outputs a voltage based on the input voltage, an output from the encoder, and an output of the random number generator.
