Non Destructive Readout (NDR)
The sensor can also be read out in a non destructive way.
After a pixel is initially reset, it can be read multiple times
without resetting. The initial reset level and all intermediate
signals can be recorded. High light levels saturate the pixels
quickly, but a useful signal is obtained from the early
samples. For low light levels, use the latest samples.
An active pixel array is read multiple times and reset only
once. The external system intelligence takes care of the
interpretation of the data. Table 2 summarizes the
advantages and disadvantages of non-destructive readout.
Table 2. ADVANTAGES & DISADVANTAGES OF NDR
Advantages Disadvantages
Low noise, because it is true
correlated double sampling
(CDS).
High sensitivity, because the
conversion capacitance is
kept low.
System memory required to
record the reset level and the
intermediate samples.
Requires multiples readings of
each pixel, thus higher data
throughput.
Figure 10. Principle of NDR
time
High dynamic range, because
the results includes signal for
short and long integrations
times.
Requires system level digital
calculations.
OPERATION AND SIGNALLING
The signals are classified into the following groups:
? Power supplies and grounds
? Biasing and analog signals
? Pixel array signals
? Digital signals
? Test signals
Power Supplies and Ground
Every module on chip including column amplifiers,
output stages, digital modules, and drivers has its own power
supply and ground. Off chip, the grounds can be combined,
but not all power supplies may be combined. This results in
several different power supplies, but this is required to
reduce electrical cross-talk and improve shielding, dynamic
range, and output swing.
On chip, the ground lines of every module are kept
separately to improve shielding and electrical cross talk
between them.
An overview of the supplies is given in Electrical
Specifications on page 4. The maximum currents mentioned
in the specifications table are peak currents which occur
once per frame (except for Vres_ds in multiple slope mode).
All power supplies should be able to deliver these currents
except for Vmem_l and Vpre_l, which must be able to sink
this current.
The maximum peak current for Vpix should not be higher
than 500 mA. Note that no power supply filtering on chip is
implemented and noise on these power supplies can
contribute immediately to the noise on the signal. The
voltage supplies Vpix and Vaa must be noise free.
Startup Sequence
The LUPA4000 goes in latch-up (draw high current) when
all power supplies are turned on simultaneously. The sensor
comes out of latch-up and starts working normally as soon
as it is clocked. A power supply current limit of 400 mA is
recommended to avoid damage to the sensor. Avoid the time
that the device is in the latch-up state, so clocking of the
sensor should start as soon as the system is turned on.
To avoid latch-up of the sensor, follow this sequence:
1. Apply Vdd
2. Apply clocks and digital pulses to the sensor to
count 1024 clock_x and 2048 clock_y pulses to
empty the shift registers
3. Apply other supplies
