Abstract
A Folding Comparator circuit which receives an analog input current and both compares it to a DC reference current while at the same time folding the input current around the reference current to be passed on as an output current which can then be passed on to another folding comparator stage. A series of such stages connected together with some XOR logic gates can perform an analog to digital conversion process as a pipeline of auto-folding stages which will instantly convert analog signal to digital signal.
