Manual amplifier nulling circuits are simple topologies, typically consisting of just a trimmer pot and a couple of fixed resistors intended to allow offset adjustment by a (usually small) symmetrical fraction of bipolar supply voltages. So, ...
In many electronic circuits, there is always a demand for a device to isolate or separate one circuit from another. This special device is called a buffer. A buffer is a unity-gain amplifier that has an extremely high input resistance and an ...
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 ...
