Abstract
A circuit for extending the dynamic range of an electronic circuit is provided. The circuit includes a first adjustable attenuation circuit having an input and an output and a control input. The control input is adapted to receive a control signal that adjusts the relative gain of the attenuation circuit. The circuit also includes at least one additional attenuation circuit coupled in parallel with the first adjustable attenuation circuit. The at least one additional attenuation circuit has a control input that is adapted to receive a control signal that adjusts the relative gain of the at least one additional attenuation circuit. The first and the at least one additional attenuation circuits are selectively controlled to adjust the level of signals in different frequency bands so as to extend the dynamic range of signals to be processed by the electronic circuit.
