The ARINC (Aeronautical Radio Inc) 429 specification defines the air transport industry's hardware and protocol standards for the transfer of digital data between avionics systems. Circuitry that can implement elements of the 429 spec is often ...
This Design Idea significantly improves conversion efficiency of externally driven flyback converter-based capacitor charging units intended for flash-lamp-pumped, pulsed solid-state laser sources. In a flash-pumped pulsed solid state laser source, ...
Frequent design idea contributor, Peter Demchenko, recently published “Extending the resolution of a peripheral DAC” ( Reference 1 ). In it, Peter describes an inverting dual-supply amplifier circuit that he says is intended “ to ...
This design idea (Figure 1) shows how easily “new flesh can be added to the old bones” and how some new functions can be added to the simple LED display that was published earlier ( Reference 1 ). Figure 1. Upgraded simple LED display ...
“The unfortunate relationship between servo systems and oscillators is very apparent in thermal-control systems,” said Linear Technology's Jim Williams ( Reference 1 ). Although high-performance temperature control looks simple in ...
There are several applications in which pulses longer than the set width are to be detected, ignoring the other short pulses. We are familiar with the missing pulse detector circuit, which detects the occurrence of a missing pulse in a pulse train ...
On two days in the course of every year, one in March heralding the start of spring and another in September marking the first of fall, the Earth’s axis of rotation aligns perpendicular to the rays of the Sun. These days are the equinoxes ...
A traditional implementation of an absolute-difference function comprises a difference circuit followed by an absolute-value circuit; the entire circuit requires at least three op amps. The design problem is complicated in single-supply-only ...
The use of multiplexer chips (typically various members of the 405x family) to control gain in transimpedance (current to voltage conversion) signal-processing and data acquisition op-amp circuits, is an established practice. Using a multiplexer ...
The control of electronic potentiometers in most today's applications comes from controller-generated signals. However, a significant number of applications exist that require adjustments using manual, front-panel controls. The circuit in ...
