ABSTRACT:
A non-linear amplifier system comprises two amplifier stages, a limiter and correction stage and a combining stage. The first amplifier stage amplifies low input signal levels linearly and higher input signal levels non-linearly. The limiter and correction stage amplifies linearly input signal levels corresponding to low input signal levels of the first amplifier stage. The second amplifier stage amplifies non-linearly input signals corresponding to low input signal levels of the first amplifier stage. The combining stage combines the output voltage signals of the first and second amplifier stages and the limiter and correction stage. For a range of low input signal levels, the output voltage signal of the combining stage is representative of the output voltage signal of the second amplifier stage, for a range of high input signal levels, the output voltage signal of the combining stage is representative of the output voltage signal of the first and second amplifier stages, and for a crossover range of input signal levels, which is intermediate the low range and the high range, the output voltage signal of the combining stage is representative of the output voltage signal of the second amplifier stage.
