Patent ID: 7180366

Claim:
An apparatus including data signal amplifier circuitry with multiple signal gains, comprising: sampling amplifier circuitry responsive to at least one control signal and an input signal having an input signal value by providing at least one sample signal having a plurality of sample signal values, including maximum and minimum sample signal values, and corresponding to said input signal value; and processing circuitry coupled to said sampling amplifier circuitry and responsive to said at least one sample signal and one or more processing control signals by processing said at least one sample signal to provide a processed signal having a value corresponding to said input signal value; wherein said processing circuitry is adapted to provide said processed signal such that said processed signal value represents one of a plurality of values which includes said maximum sample signal value, said minimum sample signal value, a first one of said plurality of sample signal values, and a combination of said first one and at least a second one of said plurality of sample signal values.
