ASD00A CMOS ASD Front-End Development

We have developed an 8-channel Amplifier/Shaper/Discriminator (ASD) chip for the readout of MDTs. This chip is all-CMOS, with low noise, precision timing and low power consumption.

Octal ASD Development

Octal II Prototype (final? version) fabricated and under test (7/01).

Octal I Prototype (full function) fabricated and tested. All okay except for some minor problems with DAQ ranges, etc.

ASD Lite (10k channel) program

About 4,400 ASDLite chips (17k channels) have been produced and packaged, and are being tested.  See slides with status report and some photos.  Matching mezzanine boards have been prototyped and will be produced in quantity shortly.

See Data Page for ASDLite chip.
