Abstract
An integrated detection circuit (10) linearly charges capacitors (14) and (16) over time in response to particular states of an input signal (12). Outputs from the integrated detection circuit (10) are generated by differential pairs (39) when the charge on either of the capacitors (14) or (16) is equal to or greater than a reference voltage input to the differential pairs (39).
