Description

We present results from a capacitor charge pump DC- DC converter prototype using 0.35um HV-CMOS technology fabricated in April 2006. The purpose of this prototype is to test the switch technology both for achievable efficiency and for radiation tolerance. The IC of this test device contains only switches, with all clocks being externally supplied and driven and the capacitors also external. The configuration used is a 4 capacitor stack producing a nominal x4 input current multiplication factor. The goal for this type of device is to be of low enough mass and high enough radiation tolerance to be placed on individual modules in the innermost layers of the ATLAS detector. Irradiation results will be presented if available. A prototype test card for use with a silicon strip stave prototype is under development.

Summary

We present results from a capacitor charge pump DC-DC
converter prototype using
0.35um HV-CMOS technology fabricated in April 2006. The
purpose of this prototype is
to test the switch technology both for achievable efficiency
and for radiation
tolerance. The IC of this test device contains only switches,
with all clocks being
externally supplied and driven and the capacitors also
external. The configuration
used is a 4 capacitor stack producing a nominal x4 input
current multiplication
factor. The goal for this type of device is to be of low enough
mass and high enough
radiation tolerance to be placed on individual modules in the
innermost layers of the
ATLAS detector. Irradiation results will be presented if
available. A prototype test
card for use with a silicon strip stave prototype is under
development.
