Single-ended/push-pull converter

A single-ended/push-pull converter for converting a single-ended input signal into a push-pull output signal, comprising a current mirror arrangement with a low-ohmic input circuit and a high-ohmic output circuit, the current in the output circuit bearing a fixed ratio to the current in the input circuit, a first transistor whose emitter circuit includes the output circuit of the current mirror arrangement and whose collector electrode is connected to a point of constant potential via the series connection of at least a first impedance and the base-emitter junction of a second transistor, of which second transistor the collector constitutes a first push-pull output, while an electrode of the first transistor constitutes the single-ended signal input, a third transistor of the same conductivity type as the first transistor, of which third transistor the emitter circuit includes a second impedance and the input circuit of the current mirror arrangement, and of which third transistor the base electrode is coupled to the collector electrode of the first transistor, and the collector constitutes a second push-pull output, and a d.c. blocking impedance which shunts the output circuit of the current mirror arrangement.
