Description
The needs for increasingly low cost, low space occupancy and
reduced weight in the space industry have made mixed-signal
ASIC integration mandatory.
The aim of the contract was to develop, qualify and deliver
the flight models of the mixed Analog/Digital ASIC, named
ACCORC7 or IM485A for the CODECHAMP Company. It is
a high resolution optical encoder and polarimetric position
sensor.
In a first contract, the CNES and ID MOS selected the mixed-
signal XH035 LV technology to design a set of rad-tolerant
Low Voltage ELT transistors, checked their robustness up to
total ionizing dose of 100Krads and their immunity to the
Single Event Latch-up under heavy ions.
The design of those transistors made it possible to reach the
required radiation level and the characterization of these basic
elements made it possible to have reliable simulation models
in order to secure the result from the first Silicon run.
Once the prototypes were validated by CODECHAMP, ID
MOS launched a production batch for the qualification and
delivery of the flight models.
