- Background
- The SIDECAR ASIC was developed by Teledyne
Scientific Imaging, LLC in an effort to
streamline the normally bulky and power-hungry
focal plane-electronics which are used to control
imaging sensors. - The SIDECAR can generate the necessary clock
signals and bias voltages needed to operate the
detector while simultaneously digitizing detector
outputs. - Reducing the size and mass of the detector
control electronics is important in space
missions which have mass limits. This device will
be used on the Hubble Space Telescope. The
SIDECAR will be used on the James Webb Telescope
as well.
ABOVE Detector control electronics built by
Astronomical Research Cameras, Inc. The SIDECAR
has the same capability as this set of
electronics.
ABOVE Sidecar ASIC. All signal conditioning,
clock/bias generation and digitization hardware
is self-contained in this small chip.
- Testing
- The Sidecar ASICs baseline performance must be
measured and tested with respect to its various
modes of operation, firmware settings and
experimental setups. - The Sidecars firmware must also be pared down
to a simple linear readout format, minimizing the
amount of noise from signal conditioning and
processing. - Once a baseline operational mode is achieved,
the Sidecar is subjected to a battery of standard
tests for digitization hardware and analog
electronics. - These tests will be important in determining the
optimal configuration for the SIDECAR for any
given application. Thus allowing us to better
control imaging sensors and optimizing their
performance.

ABOVE SIDECAR read noise results from two
distinct setups in an experiment to remove a
noise pattern. In this experiment, one input
channel on the SIDECAR was fed a 1V DC signal
from a power supply. In SETUP A the ASIC was
powered by an AC/DC converter via the USB cable.
In SETUP B the SIDECAR is powered by the laptop
battery via the USB cable. The noise difference
in the two setups can be attributed to the power
source for the ASIC. This is an example of the
tests needed to be preformed to determine the
optimal operation of the SIDECAR.
