Description

ABSTRACT:
The present invention describes a bipolar impedance converter circuit, which comprises a differential amplifier that has a closed-loop control circuit in its negative feedback loop. This closed-loop control circuit comprises npn transistors, which because of their relatively low stray capacitances and their fast switching speed provide an impedance converter circuit with greater invulnerability to disturbances in the supply voltage and have faster switching behavior than known circuits in the prior art, which use pnp transistors in their negative feedback loop.
