headphoneAmp bandwidth
A simulation of the headphone amp to determine the bandwidth yields a 30 dB peak around 75 Hz, at 1 KHz the amplitude is -45 dB. Using an LT1055 produced the expected results, a bandwidth of about 1...

Re: Hitting The Global Warming Button
1. The world may not be warming at all; it could well be instrumentation errors. Just the change in paint on Stevenson boxes could explain the whole thing. 2. The planet's temperature is very noisy on...

Simulating Power Bandwidth
I'm trying to do a simulation to show power bandwidth for a (high power) OpAmp versus compensation capacitor. In the lab I would simply crank up the signal generator amplitude until the output became...

Faster buffer than NL37WZ16US anywhere?
Folks, The NL37WZ16US can muscle a 50ohm load around in under a nanosecond when paralleling all three sections in it. This is great. But of course once you have a Porsche you then want a Ferrari. Is...

manifesto
This is cool: We can probably expect cheap power fets with something like 100x the power/capacitance ratio of mosfets. Get used to designing 40 MHz class-D amps and switching supplies.

Vaccum capacitor failure oddness.
While analyzing a problem with a small (150Kwatt oscillator) circuit, we discovered a faulty 200 pf 30VK vacuum cap. This was found via a series of HI-POT testing, starting with the filament...
