Abstract: An integrated analog to digital interface subsystem for imaging applications includes digital global and digital pixel by pixel offset correction and scaling. The integrated interface 2 includes 3 DAC's 2c1-2c3 that are used to do a rough offset cancellation on the three analog input signals (RGB) in the analog domain. A triple sample/hold circuit 2a samples the RGB signals simultaneously, multiplexes the data and passes the three signals on the ADC 2b sequentially (at about 3 times the data rate). The sample/hold circuit 2a has the capability to operate in fully differential as well as single ended input mode, and can perform correlated double sampling if needed. A high resolution ADC 2b converts the 3 multiplexed signals from simple/hold circuit 2a. A first digital offset correction circuit 2f restores the level of the RGB signals in the digital domain on a pixel by pixel basis.
