Resonant circuit design
In e.g. VCO design, assuming a less than ideal varactor/varicap, is there a particular resonant circuit/tank topology or ratio of components where given a base operating frequency with no control...

MPPC front end with SAV-551+ pHEMT bootstrap
So I'm doing this multi-pixel photon counter front end for a SEM cathodoluminescence detector. The proto uses a Hamamatsu S13362-3050DG cooled MPPC running at a gain of about 1.7E6, so each...

Simple salt-water detector, go/no-go type discrimination or better?
Any ideas. It will not be permanently immersed in salt-water, just the odd sampling. Ancient unmaintained sewer system has breaches to tidal sea-water at high tides from cracked and dislodged...

Harvesting energy from 3-phase
A customer has a three-phase supply drawing from 50A to 100A at nominally 60Hz. He wants to tap some power from this without any electrical contact, so probably using say three current transformers...

Low voltage negative resistance oscillator design, lessons learned
Don't bother with discretes if you want a negative resistor when you have low psu headroom, all the discrete negative resistance topologies, lambda diodes, foldback limiters, etc. are bad at a couple...

Amplification factor for common emitter amplifier
Is it possible to calculate the amplification factor for an amplifier,, e.g., a common emitter amplifier. This is because the amplification depends very much on the biasing condition, and so without a...
