The term bandwidth is used and abused in many situations. I recall one meeting where the word was used to refer to: the frequency content of a particular signal, the frequency response of a specific circuit, the speed of our local area network and ...
This design based on an SR latch and two RC networks is, unlike many alternative solutions, neither complex nor expensive. Single and differential capacitance sensors are widely used to measure linear and angle displacement, pressure, proximity, ...
Multicore processing boosts performance and energy efficiency in many coding situations. Bare-metal algorithms further enhance these benefits. Many embedded firmware engineers have seemingly not yet tried multicore processing. Using processors with ...
Abstract This article discusses the need for precise gate voltage control and accurate gate measurements when using gallium nitride field-effect transistors (GaN FETs). High-side gate measurements taken with advanced isolated probes are compared to ...
The circuit in Figure 1 combines a V BE -referenced current source with a current mirror to implement a simple two-terminal, fully floating LED current sink or source. This approach is well-suited for applications in which tight current accuracy is ...
After more than fifty years of continuous production in bipolar and fully half that in CMOS, there’s really neither room nor reason to question the value and versatility of the venerable 555 analog timer. But if it has any significant ...
Abstract This power management tip introduces the two different circuits for a positive-to-negative voltage conversion and for a negative-to-positive voltage conversion. It explains how a step-down (buck) regulator circuit may easily be modified to ...
We regenerate these type of alkaline batteries [1] here: (not normal rechargable ones ) The schematic The schematic is rather trivial (Fig. 1). A voltage regulator brings down a supply voltage (which might be from a car battery) to 5 V. An ...
Modern high-speed RS-485 data links are pushing the envelope to the absolute breaking point with regards to data rate versus cable length. Applications include position encoders, traffic monitoring, seismic networks, and GPS transceivers. Data ...
In this Design Idea (DI), the classic Schmitt-trigger-based RC oscillator is “hacked” and analyzed using the simulation software QSPICE ( Ref. 1 ). You might reasonably ask why one would do this, given that countless such circuits ...
