Claims19
An apparatus comprising:
- a first amplifier comprising first input terminals and first output terminals, wherein the first amplifier is to amplify an input signal provided to the first input terminals and to provide the amplified input signal to the first output terminals;
- a second amplifier comprising second input terminals and second output terminals, wherein the second input terminals are operatively responsive to a second input signal and wherein the second amplifier is to amplify the second input signal and provide the amplified second input signal to the second output terminals;
- and
- a coupling device to provide operative responsiveness by the second input terminals to the first output terminals, wherein a common mode voltage at the first output terminals and the second input terminals are approximately equal.
