Abstract
A photodiode structure () includes a first plurality of co-located light band detectors that generate analog detector signals, a first multiplexing circuit () coupled to the first plurality of analog detector signals, which sequentially generates each of the first plurality of analog detector signals at a first multiplexed output (), a second multiplexing circuit () coupled to a first plurality of reference signals, which sequentially generates at a second multiplexed output () each of the first plurality of reference signals in synchronism with the first multiplexed output (); and a single digital pixel sensor circuit () having inputs coupled to the first and second multiplexed outputs, which sequentially generates a series of digital outputs based on the first and second multiplexed outputs ().
