Patent ID: 7692453

Claim:
A differential voltage overlap detector comprising: a pair of differential input voltage receiving means, each pair of receiving means configured for accepting a pair of differential voltage components; a pair of current steering means, each pair of steering means being capable of producing said internal differential voltage component complementary to the other; a pair of electrical current sources, each current source being configured to couple between a positive voltage supply and an input of one of said pair of current steering means, said electrical current sources being further configured to supply sufficient current to sustain an internal differential voltage at a node of one of said differential voltage components; a differential amplification means for generation of an output detection signal from each of said internal differential voltage components of said pair of current steering means; and a pair of electrical charge storage means, each storage means capable of a retention of an integrated electrical potential to an input of said differential amplifier, wherein the pair of electrical charge storage means is respectively coupled in parallel with the pair of current steering means.
