One embodiment of the present invention is a Gray code current-mode analog to digital (ADC) converter using a Gray code current-mode ADC building block. The Gray code current-mode ADC building block can produce a Gray code bit and a current output that is sent to a next Gray code ADC building block. In one embodiment, the Gray code current-mode ADC building block does not use a voltage comparator in a signal path of the current output. In one embodiment, an 8 bit analog-to-digital converter can have a 65 ns conversion time and consume only 10 mW of power with a single +5.0V supply.
