Architecture and Operation

The basic architecture of the sensor is shown in the

arrays. The imager arrays row is selected by the row drivers or
reset by them. There are two Y shift registers, one points at the
row that is read out and the other points at the row to be reset.
The second pointer may lead the first pointer by a specific
number of rows. In that case, the time difference between both
pointers is the integration time. Alternatively, both shift registers
can point at the same row for reset and readout for a faster reset
sequence. When the row is read out, it is also reset. This is to do
double sampling for fixed pattern noise reduction.
The pixel array of the IBIS4-14000 consists of 4536 x 3024 active
pixels and 24 additional columns and rows which can be
addressed (see
pixel information and perform the double sampling operation.
They also multiplex the signals on the readout buses which are
buffered by the output amplifiers.
The shift registers can be configured for various subsampling
modes. The output amplifiers can be individually powered down
and some other extra functions are available. These options are
configurable via a serial input port.

Figure 2. Pixel and Column Structure Schematic
Architecture
The pixel is a classic three transistor active pixel. The photodiode
is a high-fill-factor n-well/p-substrate diode. The chip has
separate power supplies for the following:
■

■
FPN and PRNU
Fixed Pattern Noise correction is done on-chip using the Double
Sampling technique. The pixel is read out and this voltage value
is sampled on the capacitor SHS. After read out the pixel is reset
again and this value is sampled by SHR. Both sample and reset
values of each pixel are subtracted in the column amplifiers to
subtract FPN. Raw images taken by the sensor typically feature
a residual (local) FPN of 0.11% RMS of the saturation voltage.
The Photo Response Non Uniformity (PRNU), caused by
mismatch of photodiode node capacitances, is not corrected
on-chip. Measurements indicate that the typical PRNU is less
than1% RMS of the signal level.
RESET
General power supply for the analog image core (VDD)
Power supply for the reset line drivers (VDDR)
Separate power supply for the pixel itself (VDDARRAY).
