Abstract:
A processor and configurable amplifier system, said system comprising:a processor; an amplifier having an input and an output; a first switch having a plurality of inputs and an output; a second switch having an input and an output; said first and second switches controlled by said processor; a plurality of gain determining elements connected to the inputs of said first and second switches; said second switch output coupled to the output of said amplifier; and said first switch output coupled to the input of said amplifier; wherein said amplifier is configured as a general purpose amplifier without gain determining elements connected thereto when said first switch selects a first one of the plurality of inputs and said second switch is off, and said amplifier is configured as a programmable gain amplifier when said first switch selects any other one of the plurality of inputs and said second switch is on, whereby said gain determining elements determine the gain of said amplifier.
