Leti recently miniaturized a key component for the testing and measurement market

​Greenfield Technology turned to Leti, a CEA Tech institute, to develop an electronic delay component with picosecond resolution. The development will help the company address new markets from a position of competitive advantage.

Published on 8 December 2017

Large physics instruments like high-power lasers, synchrotrons, and particle accelerators are all equipped with delay generators that coordinate events within a very short timeframe (10-12 second). Greenfield Technology, a company that designs and manufactures measurement and testing equipment for research, turned to CEA Tech's Nouvelle Aquitaine regional center for support developing a delay component.

Specifically, Leti was asked to miniaturize an existing delay generator built from surface-mounted devices. The solution was to integrate several delay functions onto a single CMOS integrated circuit. The circuit, which boasts four independent delay channels, offers exceptional precision, very high resolution (with an adjustment pitch of less than 1 picosecond), very low jitter, and very good stability. The circuit also includes a self-calibration feature and I/O interfaces that comply with major industrial standards (PECL, SPI, 3.3 V input, QFN). The component's groundbreaking features and performance will help Greenfield Technology remain competitive.

An initial prototype is currently being tested. The early results show that most of the specifications have been met.
