Abstract:
An analog-to-digital converter (110) comprises an analog signal input (122) for receiving an analog signal and an amplifying stage (160) configured to generate a set of N amplified analog signals, where N is an integer ≥2. The set of N signals have different gains. The ADC has a ramp signal input (121) for receiving a ramp signal and a clock input (143) for receiving at least one clock signal. A comparison stage (120) is connected to the set of amplified analog signals (SigG1, SigG2) and to the ramp signal input (121). The comparison stage (120) is configured to compare the amplified analog signals with the ramp signal to provide comparison outputs during a conversion period. A control stage is configured to control the counter stage (140) based on the comparison outputs and a selection input indicative of when at least one handover point has been reached during the conversion period.
