Patent ID: 7183850

Claim:
An amplifier comprising: an input stage comprising an input operably configured to receive an input signal, a first input path operably connected to the input and comprising at least one transistor element, a second input path comprising at least one transistor element, the second input path parallel to the first input path and operably connected to the input, a first biasing voltage connection operably connected to the at least one transistor element of the first input path and switchably connected to the at least one transistor element of the second input path, and an input stage output operably connected to the first input path and to the second input path and configured to output the received input signal; and an output stage comprising a first output path operably connected to the input stage output and comprising at least one amplifier, a second output path comprising at least one amplifier, the second output path symmetrical to the first output path and operably connected to the input stage output, a second biasing voltage connection operably connected to the at least one amplifier of the first output path and switchably connected to the at least one amplifier of the second output path, and an output operably connected to the first output path and to the second output path and configured to output an amplified received input signal.
