Abstract
Disclosed is a method of comparing two or more signals which may include: for each of the two or more signals, charging to a fixed voltage a compensation capacitor associated with a sense path of the signal, discharging each of the charged capacitors to a threshold voltage of a transistor in its respective sense path and integrating a discharge current from each capacitor with the signal sensed on the respective sense path.
