... Description The ACS Image Sensor consists of an array of low dark current photo-diode pixels coupled to patented Active Column Sensor (ACS compared to alternative CMOS and CCD image sensors on the market today. Each pixel contains a storage site, allowing electronic shutter or adaptive exposure control. These Imaging systems may be controlled externally, or operate completely autonomously using the on-chip configuration registers and programmable multi-mode controller ...

... All descriptions herein involve row operations unless otherwise noted. Referring to Figure # 1, at the top of the drawing is the dual gate Select FET of the Active Column Sensor (ACS). This dual gate FET has the dual purpose of selecting a row of pixels as well as sensing the accumulated charge within the pixel. The Row Select line turns each row of Select FETs “on”. ...

... Selected and deselected to re-bias the pixels the reset value and the background. These are the standard methods allowed and controlled internally by the ACS sensors series. If the imager is operated in the slave mode, greater operator control allows more flexibility, to minimize the number of operations performed per frame of Video and potentially reduce the associated noise generated ...

... Upon the completion of CDS, the CDS Timer issues an End Of CDS (EOC) indicating that there is valid data on the video output bus. As the ACS is randomly addressable, the CDS timer has no knowledge of the size of the array area to be readout. The ACTIVE signal must be set TRUE and stay TRUE until readout of the desired pixels is completed. After readout completion releasing the ACTIVE signal, allows the CDS timer to finish end of row events ...

... The differential amplifier requires a “background sample” to operate correctly. However in mode 2 the PD and SS must be electrically connected to sample the video amplitude. When the ACS is switched to mode 2, it stores the background sample from the previous frame for this purpose. While in mode 2 no CDS is actually taking place, to subtract the background during final readout ...
