[time-nuts] Dual Supplies for Low Offset Phase Noise Analyzer

[Bob Martin]

Erik,

I think you'd be better off  with dual supplies and take advantage
of the amplifier PSRR. I'd put a reverse Schottky diode to ground at
the output of each regulator to ensure startup. On some regulators,
a reverse voltage on the output can inhibit regulation. There is
a lot to be said for a ground reference that is a ground plane as 
opposed to some floating reference voltage when worknig with low 
signal levels...

Best,

Bob
