I have the simple problem of trying build a circuit that turns a
~8-15Mhz, ~100mV-2V sine wave into a DC level (for read out by an ADC).
I've tried just rectifying and putting an RC to hold the DC level, but
I don't seem to get a flat response over the specified frequency
range. The sine wave will change amplitude over seconds, but no faster
than that. Any ideas, or am I just not good enough at making
rectifiers with caps (which is very possible).
