A prototype integrated circuit is described which uses a 32-phase clock to record the arrival time of incident particles. The chip architecture is such that data can be acquired continuously to a timing resolution of 1ns and up to a peak input frequency approaching 500MHz. The device incorporates cache memory and write only if data (WOID) techniques to maximize the throughput of the chip. A novel...
A 16-channel programmable pulse generator ASIC has designed in 1.5??m CMOS technology. By employing novel design techniques time delays with 1nS time resolution have been achieved with a dynamic range of 219. Currently the chip is being used to drive ultrasonic transducer arrays.
A hybrid circuit is reported which is a novel position sensitive charged-particle detector. Multi-channel detectors have been developed which consist of an array of charge sensing electrodes and a corresponding array of amplifiers and counters integrated on a single chip. The active electrode area can be arbitrarily extended by abutting individual detector chips side-by-side, under the control of...
The object of this research was to design and fabricate a linear array of electron sensing electrodes coupled to detection and read-out circuitry in the form of amplifiers and counters integrated onto a single CMOS chip. The chip replaces existing position-sensitive detection systems in electron spectrometers.
