[time-nuts] Need tiny 5MHz 10x amplifier

[Poul-Henning Kamp]

I need to convert a 5MHz 0.2Vpp AC coupled sine signal to a 3.3V
CMOS compatible logic signal.

The "default" comparator based circuit either requires a negative
supply or 4 resitors for biasing the input and setting the zero level.
(The hysteresis resistor is the same in both cases).

Since space is a bit tight, I've been trying to find something like
a "x10 self-biasing amplifier" but without luck.

Any good ideas ?
