Many power applications ranging from luminescent and fluorescent lighting to telephone-ringing voltage generators require a more or less sinusoidal-drive voltage. These applications typically require ...

We have already given many posts on Op-Amp circuits. But the list of applications of Op-Amp will be keep on going. The best Op-Amp circuit which is used to convert sine waveform into rectangular ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

Fig. 1: The dimmer circuit schematic showing the filtering capacitors. Rob Atkinson, K5UJ, is an engineer out of Saint Charles, Ill., and one of the many readers who enjoy the DIY projects we feature ...

This file type includes high resolution graphics and schematics. Although quite a few direct digital synthesis (DDS) ICs can generate high-frequency sine waves, their complexity excludes them from ...

Engineers often face design goals with conflicting requirements. For instance, take a design that requires an input capacitor to stabilize the bias voltage and present clean dc power to the device’s ...
