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 ...
Applications such as audio equalizers require bandpass filters with a constant maximum gain that's independent of the filter's quality factor, Q. However, all of the well-known filter architectures Sallen-Key, multiple-feedback, ...
We’re all familiar with thermally activated fuses, where the conducting element self-heats due to current flow, melts at a defined current value, and breaks the flow path. They are simple in concept (although they have their own subtleties, ...
I have always been intrigued by the many ways scientists and engineers have devised to sense basic physical parameters such as temperature, pressure, voltage, current, and electric fields, to cite just a few. In some cases, the challenge is the ...
Any semiconductor has limits on how much voltage, how much current, and for how much time combinations of voltage and current can be supported in normal usage. Sometimes that information is provided as part of the device’s datasheet, and ...
Abstract This article describes a circuit that facilitates the measurement of currents from amps to hundreds of amps with a high degree of precision. Introduction There are many applications that require the measurement of current. Many digital ...
With the trend toward miniaturization, temperature effects in power electronics are more pronounced than ever. If you’re dealing with temperature fluctuations in your circuit, you may need a stabilization system to keep the temperature ...
