Abstract
A method and apparatus for analog-to-digital conversion. An Analog-to-Digital Converter (ADC) includes M ADC, j=1, 2, . . . , M. Each ADCcomprises a number of cells each of which comprises a first switch, a second switch, a current sink and an inverter. An inverter of a cell in an ADCchanges state in response to a current associate with an input signal of the ADCexceeding a threshold, thus switching on the next cell. Each ADCis enabled to perform analog-to-digital conversion on a residual current of a previous ADCafter the previous ADChas completed its analog-to-digital conversion and has been disabled.
