A unique design flexibility that can either extend the maximum operating frequency of a power amplifier or allow the use of larger active devices with higher power handling capability. This paper ...

The nominal impedance of a magnetic headset isn't necessarily a good description of its actual impedance as a function of frequency. A headset's fairly complex equivalent circuit may even lead to ...

According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

Abstract: Many industrial/scientific/medical (ISM) band radio frequency (RF) products use crystal oscillators to generate a reference for the phase-locked loop (PLL)-based local oscillator (LO). This ...

This tutorial explains the primary design considerations to be addressed in a design of a simple crystal oscillator using AT-cut crystals. The basic qualities of a crystal oscillator and factors that ...

Piezoelectric shunt damping is an innovative method for mitigating unwanted vibrations in structures by exploiting the electromechanical properties of piezoelectric transducers. When bonded to a ...

In today's world of increasing electrical noise, higher-speed logic, and more-sensitive circuits, the need for high-frequency noise filtering is especially critical. Noise can enter a circuit through ...

Northeast Utilities has purchased four of Siemens Power Transmission & Distribution, Inc. new 550-kV dead tank circuit breakers with FA5 spring-spring operator technology – the first of their kind in ...
