Abstract
A desired non-linear, monotonic compression function is performed substantially symmetrically upon both polarities of an AC signal by a circuit having a plurality of limiting stages, each having input circuitry with like terminals connected in parallel to one another, and providing an output current proportional to the stage input voltage, with a gain constant decreasing for an increasing stage number. Each stage has output circuitry connected in parallel with one another and providing an output current proportional to the stage input voltage, with a gain constant decreasing for an increasing stage number. A single output stage converts the total current provided by the limiter stages to an output voltage.
