Forum Post: RE: 20nH-200nH range inductance tester
OK, thank you for your effort. I found some very expensive and very cheap solutions on the Internet. Since I need only very cheap (I don't expect good revenue from this action) modulation-based analog...

View ArticleForum Post: MSP430 reset specification
Hi, This is about the MSP430's reset, ​ On the MSP430F5171 datasheet, the reset pulse duration time is mentioned as tRESET=2us(min), but falling edge timing is not mentioned in the datasheet. Please...

Sounds perhaps simpler as it is. Designing an amplifier in the MHz range with a stable output amplitude is not trivial, neither is factoring in the parasitic capacitances/inductances and temperature...

I would pick "resonance circuit with a known capacitor" too. Gilbert cell as LC tank oscillator, feed output into lab frequency counter and that' s it. If you don't have counter then build one using...
