Source follower with bip. Trans and bootstrapping for impedance increase

Leo Baumann · 2019-04-20T01:43:35+00:00

Rolf Bombach has proposed the following circuit to increase the input impedance of a source follower with bip. Trans. And Bootstrapping: The real part of the input impedance at 100 MHz is now 2.57 kOhm. The input capacitance at the gate is only 1 / (608.55883 kOhm * 2 * Pi * 2 MHz) = 131 fF. wow - awesome for some applications
