Although an analog moving-coil meter may lack the resolution and accuracy that a digital readout provides, a meter remains the display of choice for certain applications. A digital readout simply cannot provide information about a measurement's rate of change, and tracking a reading's trend is easier on an analog meter....

A previous Design Idea describes an interesting and useful method for using a moving-coil analog meter to measure currents in the less-than-1A range. The design offers considerable flexibility in the choice of meter-movement sensitivity and measurement range and simplifies selection of shunt resistors...

By using JFETs in unusual configurations, you can design simple, high-frequency LC oscillators with few passive components...

In this article, I want to talk about the method of software repair or firmware recovery of the Dahua DH-IPC-HDW4421E IP-camera...

Microchip Technology announced the release of a high-precision voltage reference (Vref) IC that meets these needs at a cost-effective price...

For several years Quad-flat no-leads (QFN) package with thermal pad have been standard starting point for high current designs. Technology and trends pushed buck converters to get even smaller and more efficient...

Diodes Incorporated introduces the PAM8965 Class-D stereo audio power amplifier with an integrated synchronous boost converter...

This circuit was born from an application that required an input signal to be precisely clamped to less than 2.5 V, while operating on a 2.5 V supply with a maximum output of 4 mA...

SiTime Corporation introduced the SiT3901 µPower digitally controlled MEMS oscillator targeting power-sensitive and space-constrained mobile and IoT applications...

A random-bit-sequence generator is basic equipment for prototyping and testing any data-transmission system. You use such a generator when measuring BER and pattern-dependent effects in a transmission system...
