| Zusammenfassung: | An amplifier stage is disclosed having junction capacitors for by-passing high frequency signals without introducing substantial signal nonlinearities. A pair of similar serially connected diodes are reverse biased between the amplifier supply potentials. The mid-point connection of the diodes is connected to the amplifier node to be by-passed paralleling the junction capacitances of the diodes with respect to a-c potential excursions. Typical diode capacitance variations resulting from changes in the reverse bias potential across a pn junction is minimized by this arrangement. |
