INTEGRATED - CIRCUIT DISCRIMINATOR WITH lo - NSEC PULSE PAIR
نویسنده
چکیده
A high-speed direct-coupled discriminator utilizing emittercoupled integrated circuits is described. The threshold is continuously adjustable between -150 mV and -1.15 V, the pulse pair resolution is 10 nsec, and the maximum continuous repetition rate is 92 MHz. Two modes of operation, clipped and dc , are provided; output widths in the clipped mode are 5 nsec, 10 nsec, or 15 nsec. The use of integrated circuits result in a complete absence of trimming adjustments. Provision is made for remote control of the threshold, mode, and width. (Submitted to Nucl. Instr.

متن کاملDesign and performance of a multi-channel, multi-sampling, PSD-enabling integrated circuit
This paper presents the design and test results of an eight-channel prototype integrated circuit chip intended to greatly simplify the pulse-processing electronics needed for large arrays of scintillation detectors. Because the chip design employs (user-controlled) multi-region charge integration, particle identification is incorporated into the basic design. Each channel on the chip also conta...

متن کاملIntegrated Receiver Channel Circuits and Structures for a Pulsed Time-of-flight Laser Radar
This thesis describes the development of integrated structures and circuit implementations for the receiver channel of portable pulsed time-of-flight laser rangefinders for industrial measurement applications where the measurement range is from ~ 1 m to ~ 100 m to noncooperative targets and the required measurement accuracy is from a few millimetres to a few centimetres. The receiver channel is...
متن کاملInfluence of Time-Pickoff Circuit Parameters on LiDAR Range Precision
A pulsed time-of-flight (TOF) measurement-based Light Detection and Ranging (LiDAR) system is more effective for medium-long range distances. As a key ranging unit, a time-pickoff circuit based on automatic gain control (AGC) and constant fraction discriminator (CFD) is designed to reduce the walk error and the timing jitter for obtaining the accurate time interval. Compared with Cramer-Rao low...
