Simple Bootstrap Circuit Diagram

This is the Simple Bootstrap Circuit Diagram. Bootstrapping the substrate of a JFET amplifier reduces the distortion caused by the non-linlearity of the JFET input capacitance. In the figure, a second feedback divider bootstraps the substrate of Ul. With R{ = 500 kQ (source impedance), THD at 10 kHz was reduced an order of magnitude.
