Search results: 2,440 Output: 31-40 Abel Raynus EDN Thermocouples find widespread use for temperature measurement in systems. During system design or testing, you must observe the system's response at different temperatures. However, it's inconvenient to heat a thermocouple ... 02-08-2018 Giovanni Romeo and Giuseppe Urbinilogia Electronic Design This power supply may seem a bit strange, since it’s not stable in voltage or in current. However, it simulates the behavior of a solar panel and can be very useful if you’re ... 23-07-2018 W. Stephen Woodward EDN The accurate transmission of analog signals over long distances in noisy industrial environments is a difficult design problem. One of the oldest solutions isolated current loops is still one of the best. This Idea For ... 18-07-2018 Herminio Martinez EDN One of the most popular circuits for amplitude control in oscillators is the soft-limiter circuit (Figure 1a). When the output voltage, V OUT (t), is small, diodes D 1 and D 2 are off. Thus, all of the input current, V IN ... 06-07-2018 W. Stephen Woodward EDN Galvanically (that is, optically or electromagnetically) isolated 4- to 20-mA current loops offer robust noise immunity and tolerate long cable runs. These advantages, combined with simple unshielded two-wire cabling, make ... 05-07-2018 Maxwell Strange EDN Forget to turn off the ceiling fan in your bathroom? Install the simple timer in Figure 1. It's located out-of-sight in the fan unit, and you turn it on via the wall switch. The circuit costs virtually nothing, using junk ... 04-07-2018 Peter Demchenko EDN Low-current switching regulator ICs often use a Darlington as the output switch. The power conversion efficiency in this case can be improved with the help of only two cheap components. To make this possible, the chip should ... 04-07-2018 John Ardizzoni EDN Designed as a high-speed driver for 12-bit ADCs, the AD8137 controls SPDT GaAs (gallium-arsenide) FET-MMIC (microwave-monolithic-IC) and PIN-diode RF switches and thus provides a low-cost and versatile alternative to conventional ... 04-07-2018 Bill Reeve Electronic Design Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and characteristic curves. The ... 20-06-2018 Eliot Johnston EDN Keeping low-voltage outdoor lights illuminated takes some effort. Bulbs burn out, and connections corrode. HB LEDs (high-brightness light-emitting diodes) seem like acceptable replacements, but most are available only in ... 20-06-2018
