Hello--
I recently found this particular advertisement for an instrument to
measure picovolt levels:
http://www.emelectronics.co.uk/spec/P12.html
I am wondering how it might be possible to measure a signal with a
picovolt resolution. Does anyone know of a book, monograph, or paper on
the measurement of small voltage levels? Where should I look in the
literature to be able to design a similar circuit?
If the signal range is from picovolt levels to 5V levels, then how would
I resolve picovolt levels while taking into consideration the higher
voltages? Perhaps some sort of log amp would work well?
Obviously, the circuit may require an op amp with a low offset voltage,
BUT how would I deal with picovolt levels?!?
