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 ...
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 ...
I’ve been working with dc power supplies and batteries for over 30 years now and every day I employ Ohm’s Law, V = I R, to solve some problem or make some calculation related to dc power. If current is flowing, then there’s a ...
Could a simple passive RC network without any transformers, inductors, switches, or non-linear components produce a voltage gain? Well, it’s not “free energy,” however, yes, and can even use the same value resistor and capacitor ...
High-resolution mixed-signal devices present an interesting challenge as you try to find the right voltage-reference design. Although no universal approach exists for these voltage-reference designs, the circuit in Figure 1 presents an interesting ...
