A PWM-controlled regulator, this time using a logic gate IC, op-amp, and resistors and capacitors to buffer the PWM signal.

By using op amps powered from a bipolar supply and ground-referencing the sensor signals, the op amp’s output will be at zero ...

This circuit makes use of negative feedback to ensure that the ripple signal is an exact replica of the signal applied on the non-inverting terminal of the op-amp. It works well for even square wave ...

Abstract: Module-level power electronics can optimize power generation ... and extinguish arc faults using the power modulation and signal processing. A non-inverting buck-boost (NIBB) converter is ...

2017 /PRNewswire/ — Trina Solar’s PV modules have commenced operations in the 10MW Sustainable City in Dubai, an innovative project that serves as living proof that developing a community ...

But as [gschmidt958] explains, this is strictly for the challenge, plus it made a nice entry in the recently concluded Op-Amp Challenge contest. His work began in simulation, exploring op-amp ...

We’re reminded of those days by [Burkhard Kainka]’s triggered sound generator, which couples an op-amp timer to another op-amp phase shift oscillator to produce a sound described as “the ...
