    Sensors such as strain gages, RTDs (resistance temperature detectors), and thermistors produce a resistance that’s proportional to force or temperature. If you measure a sensor’s resistance, you can calculate the physical parameter. ...

    From the early CRT-based tools to the latest multifunctional powerhouses, the venerable oscilloscope has long been a mainstay of electronic design. Able to graphically display a range of electronic circuit performance information as a ...

    An unshielded twisted-pair cable that is transformer-coupled to a digital system can easily act as a radiating antenna, not because of the differential analog signal the cable carries, but because of common-mode currents induced by unwanted stray ...

    Cortex-M0+ is not the newest small, low-power processor and, in fact, some newer offerings may surpass it. However, its broad deployment and mature environment continue to make the processor a compelling offering for low-power applications. So, ...

    If you need a very pure sine wave in the audio range, the circuit in Figure 1 can help. It is a simple deal: A sine wave with a THD of 1% coming from a function generator that goes through a trackable low-pass filter, which attenuates the ...

    When current pulses with a stable I HIGH /I LOW ratio modulate a semiconductor junction, the ensuing voltage difference (for example, ΔV BE for a bipolar transistor) is a linear function of the absolute (Kelvin) temperature, T. You can use ...

    The circuit in Figure 1 seems utterly simple but demonstrates unusual behavior. It produces an almost square wave of odd-integer quartz harmonics, including its main frequency. Figure 1. A simple circuit that produces an almost square wave ...

    Simulating the output-offset current of a current mirror is straightforward. You simply have to apply an input current, measure the output current, and calculate the difference. This output-offset current, however, is not equal to the input-offset ...

    Nearly four decades ago (in his Designs for High Performance Voltage-to-Frequency Converters, Ref. 1 ), famed designer Jim Williams cataloged five fundamental techniques for voltage to frequency conversion. One of those five is reproduced in Figure ...

    With the addition of a few inexpensive miniature components, the hard-wired, voltage-controlled current source of yesterday becomes a software-programmable voltage-controlled current source (Figure 1). A digital potentiometer, IC 1 in conjunction ...
