Abstract
"CIRCUITO ELETRôNICO PARA UM CONVERSOR DE ANáLOGO PARA DIGITAL DE DESCARGA CAPACITIVA". Um circuito eletrônico para um conversor de análogo para digital de descarga capacitiva para converter a razão de primeiro e segundo sinais análogos em uma representação em código digital usando uma série de ramais de comparador capacitivo paralelos. Cada ramal computando um bit do código digital simultaneamente de acordo com seu índice de série. O primeiro sinal análogo é aplicado como uma diferença de voltagem entre primeiros nós de sinais compreendendo um primeiro nó de sinal positivo e um primeiro nó de sinal negativo. O segundo sinal análogo é aplicado como uma diferença de voltagem entre segundos nós de sinais compreendendo um segundo nó de sinal positivo e um segundo nó de sinal negativo.
