Abstract
An analog-to-digital converter, comprising: a voltage to delay circuit having a voltage input, a threshold voltage input, a first output and a second output, wherein a leading edge of the first output is delayed, by a first delay magnitude, in relationship to a leading edge of the second output; and a first stage including: a first logic gate having a first input coupled to the first output of the voltage to delay circuit, a second input coupled to the second output of the voltage to delay circuit, and an output; and a first stage delay comparator having a first input coupled to the first output of the voltage to delay circuit, a second input coupled to the second output of the voltage to delay circuit, a sign signal output and a first stage delay comparator output, wherein the sign signal output represents whether the voltage input is greater than or less than the threshold voltage input. The analog-to-digital converter further includes a digital block having an input connected to the sign signal output of the delay comparator.
