A Low Power Data Acquisition Solution for High Temperature Electronics Applications

A growing number of applications require data acquisition systems that must operate reliably at very high ambient environments, such as downhole oil and gas drilling, avionics, and automotive. This article presents a new reference design for high temperature data acquisition, characterized from room temperature to +175°C.

Analyzing, Optimizing, and Eliminating Integer Boundary Spurs in Phase-Locked Loops with VCOs at up to 13.6 GHz

A phase-locked loop (PLL) and voltage controlled oscillator (VCO) outputs an RF signal at a certain frequency, and ideally this signal would be the only signal present at the output. In reality, there are unwanted spurious signals and phase noise at the output. This article discusses the simulation and elimination of one of the more troublesome spurious signals— integer boundary spurs.

Voltage References Can Bite You, Too

Why does my voltage reference have nowhere near the accuracy guaranteed on the data sheet?

Interleaving ADCs: Unraveling the Mysteries

Time interleaving is a technique that allows the use of multiple identical analog-to-digital converters to process regular sample data series at a faster rate than the operating sampling rate of each individual data converter. This technique is frequently utilized in military and electronic instrumentation applications where there is a need to continually push the state-of-the-art in data conversion speeds, resolutions, and performance. This article explains the data converter interleaving technique in technical detail as well as focusing on some of the practical challenges associated with implementing this technique.

Zero-Drift Amplifiers: Now Easy to Use in High Precision Circuits

A zero-drift amplifier, as the name suggests, is an amplifier with offset voltage drift very close to zero. It uses auto-zero or chopping technology, or a combination of both, to continuously self-correct for DC errors over time and temperature. This enables the amplifier to achieve microvolt-level offsets and extremely low offset drifts, making it uniquely suited for signal conditioning circuits that require high gain and precision performance. This article explores the architecture of Zero-drift amplifiers and provides insight into considerations for designing with these precision devices in drift-critical applications.
