Sarnoff Corporation has announced the development of four new analog-to-digital (A/D) converter macro cells for embedding in CMOS designs in which high-precision, high-speed operation at low power is important. The 8-bit, 10-bit, 12-bit, and dual 6-bit designs are available for licensing by...

A worksheet has been constructed within the Microsoft Excel software system for converting raw particle-fallout data into percentages of obscuration; that is, percentages of areas obscured by particles on surfaces. These obscuration levels are needed for assessing contamination levels in...

A proposed analog/digital circuit would improve the accuracy of determining the time of occurrence of a peak in an analog waveform. In the past, the time of occurrence of the peak was determined by comparing the magnitude of digital data samples. The time or clock pulse associated with the peak...

High-performance electronic circuits would incorporate self-checking features for detection of radiation-induced single-event latchups (SELs), according to a proposal. The basic SEL-detection scheme calls for redundant circuitry and a current-voting scheme similar to voting schemes that...

Many commercially available advanced-technology CMOS and bipolar integrated circuits are susceptible to single-event latchup (SEL) effects caused by heavy ions or protons from cosmic rays or solar flares, making them unsuitable for satellite applications. Remanufacturing the integrated circuits...

Berkeley Laboratory researchers have demonstrated a novel superconducting gradiometer that helps to reduce ambient magnetic field noise generated by relatively distant sources in favor of tiny magnetic signals generated by a local source. This is another step toward the operation of SQUID-based instruments...
