We often say that logic devices are the glue to every electronics design, but they are often the last parts that you might think about when choosing components for a system. There are certainly many tried-and-true standard logic devices to choose ...

Inverting buck-boost circuits are commonly used for generating negative supply voltages from positive voltages. The most important step is ensuring that the negative voltages are generated correctly. However, additional level shifting circuits may ...

Light and Versatile Graphics Library (LVGL) is steadily making inroads in the graphics realm by efficiently facilitating graphical user interface (GUI) designs in small, resource-constrained, and battery-powered devices such as wearables, e-bikes, ...

In today’s world, we rely primarily on streaming services to watch movies and TV shows at HD resolutions. Although a good portion of the population still takes advantage of Blu-ray players to watch media on giant-screen TVs, we’re no ...

Designers tend to favor forward- and flyback- converter topologies for loads less than 200 W because they are simple and can power multiple isolated outputs. Their simplicity is partially based on the fact that these converters use a single ...

The low- to moderate-power system in Figure 1 provides the interface between a pulse-width modulator and a high-side IGBT (insulated-gate-bipolar-transistor) or MOSFET switch. You can use it to interface TTL or CMOS circuitry to an H-bridge if you ...

In the first part of this DI ( Ref. 1 ), we saw how to gate an oscillator to generate well-behaved impulses. Now we find out how to extend that idea to producing well-behaved step functions, or nicely smoothed square waves. The ideal here is the ...

Often, one needs a simple low voltage sinusoidal oscillator with good amplitude and frequency stability and low harmonic distortion; here, the Peltz oscillator becomes a viable candidate. Please see the Peltz oscillator Analog Devices Wiki page ...

The circuit in Figure 1 computes the derivative of an input signal as the integral of the input signal minus the signal itself. Figure 1. This circuit produces less noise than the classic inverting differentiator. The response of the circuit is ...

The principle behind testing the impulse response of circuits is simple: hit them with a sharp pulse and see what happens. As usual, Wikipedia has an article detailing the process ( Ref. 1 ). This notes that the ideal pulse a unit impulse, or Dirac ...
