Abstract

An analog-to-digital converter () for an imaging device comprises an analog signal input () for receiving an analog signal from a pixel array of the imaging device and N ramp signal inputs () for receiving N ramp signals, where N is an integer ≥2. The N ramp signals have different slopes. The ADC has a clock input () for receiving at least one clock signal. A comparison stage () is connected to the ramp signal inputs and to the analog signal input. The comparison stage () is configured to compare the ramp signals with the analog signal to provide comparison outputs during the conversion period. A control stage () is configured to control a counter stage () based on the comparison outputs and a selection input indicative of when at least one handover point has been reached during the conversion period.
