2018-06-28 Bootstrapped For High Z Input

From FB group Building Transistor Radios

For those who don’t want to or can’t use a JFET for high input impedance, you can use a regular transistor or two and bootstrapping to get a 10 Megohm high input impedance amplifier. This is from “Common Collector Amplifiers”, Electronics Now, Oct. 1993,

For RFs, all capacitors can be 0.1 uF.
