A programmable gain-frequency profile amplifier is disclosed that includes a first gain amplifier amplifying an electrical signal based on a first gain-frequency profile, and one or more second gain circuits that may be programmable to substantially modify a portion of the first gain-frequency profile without appreciably modifying another portion of the first gain-frequency profile. One or more programming circuits may be connected to the second gain circuits and controlled by one or more control data inputs to turn on and off one or more of the second gain circuits. One or more capacitive coupling networks may be provided to couple the second gain circuits to the electrical signal. Each of the second gain circuits in combination with a corresponding capacitive coupling network amplifies the electrical signal based on a second gain-frequency profile which may be combined with the first gain-frequency profile of the first gain circuit to generate a composite gain-frequency profile for the programmable amplifier.
