Hi Guys
I want to build a High Speed Buffer...
I am basically building a data capture system, the receiving signal coming out from the sensor is a fixed frequency, 20MHz sinusoidal signal...amplitude varies from 20mV to 1V approximately...so I want to put a high input impedance buffer straight after the sensor stage so the signal will not be loaded or affected by the rest of the electronic circuits...
I am now thinking of PN918 transistor...but just want to know will there be some better options?
Thanks!
