ABSTRACT:
An asynchronous cyclic current-mode analog-to-digital converter (ADC) is disclosed. The ADC comprises a plurality of sub-ADCs cascading from the first stage to the last stage, each sub-ADC comprising a current-mode ADC having a digital output, an analog current input, a reference current input and an analog current output. The analog current input of each stage, except the first stage, is operatively connected to the analog current output of the immediately preceding stage. The plurality of sub-ADCs are configured to operate without synchronization with each other.
