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

a capacitor is connected directly to the inverting input of the op-amp, which contributes to a phase lag within the negative feedback loop. This affects the loop function and may make the circuit ...

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 ...
