A common problem for digital potentiometers (DigiPots) is the effect of wiper resistance, which produces quite noticeable non-linearities of regulation at both ends of the resistance range. These effects also lead to an increased tempco in these ...

Given their generally low cost, small size, robust construction, accuracy, versatility, and sensitivity, it’s no wonder that basic negative temperature coefficient (NTC) thermistors rate among the most popular temperature sensors available. ...

Electronic designers must be aware of the ideal charging method, as it increases the battery’s lifetime and enhances its performance. Nowadays Lithium-ion/Lithium-polymer are used extensively in portable electronic devices that are frequently ...

I’ve always been interested in simple-looking components which solve well-defined, clear, bounded problems. One carpentry example I encountered and used many years ago is formally known as a hanger bolt, Figure 1. One end has a wood-screw ...

The high-efficiency switching power supply has become a staple ingredient in many of today’s electronic systems. What is its origins and how has it evolved over the decades? Switched-mode power supplies are found in electronics all around us. ...

A generally accepted fact about relays and solenoids is that after they’re driven into the actuated state, only half as much coil voltage and therefore only one fourth as much coil power, are required to reliably sustain it. Consequently, any ...

Abstract This article details a method of generating dual-output voltage rails that provide both the positive and negative rails for a device power supply (DPS) while requiring only one bidirectional power supply. The traditional method of powering ...

Abstract This article will explain the inherent limitations of the boost topology and how to overcome them. When designing and evaluating boost converters, sometimes the intended output voltage is not realized. Instead, it has a lower value than ...

Figure 1 shows the architecture of a conventional isolated flyback converter. These converters can be found frequently in power classes of up to about 60 W. A supply voltage is converted to an output voltage with the help of a primary-side switch ...

Modern measurement systems often operate with single 5-V power supplies, yet their input signals may have large common-mode voltages that exceed the supply by tens or hundreds of volts. Also, unless the converter is driven differentially, the noise ...
