sensor. It consists basically of a pixel array, one X- and two
Y-addressing registers for the readout in X- and Y-direction,
column amplifiers that correct for the fixed pattern noise, an
analog multiplexer, and an analog output amplifier.
The left Y-addressing register is used for readout operation.
The right Y-addressing register is used for reset of pixel rows.
In multiple slope synchronous shutter mode, the right
Y-addressing register resets the whole pixel core with a
lowered reset voltage. In rolling curtain shutter mode, the right
Y-addressing register is used for the reset pointer in single and
double slope operation to reset 1 pixel row.
Most of the signals for the image core are generated by the
on-chip sequencer. Some basic signals (like start/stop
integration, line and frame sync signals, etc.) have to be
generated externally.
A 10-bit ADC is implemented on chip but electrically isolated
from the image core. The analog pixel output has to be routed
to the analog ADC input on the outside.

Pixel
The pixel architecture and the color filter array are described
below.
Architecture
The pixel architecture used in the IBIS5-B-1300 is a
4-transistor pixel as shown in
implemented using the high fill factor technique as patented by
Cypress (US patent No. 6,225,670 and others). The 4T-pixel
features a snapshot shutter but can also emulate the 3T-pixel
by continuously closing sampling switch M2. Using M4 as a
global sample transistor for all pixels enables the snapshot
shutter mode. Due to this pixel architecture, integration during
read out is not possible in synchronous shutter mode.
