Abstract:
A circuit includes an amplifier including a differential input stage including a first input terminal and a second input terminal. The circuit further includes a differential input line coupled to the first input terminal and the second input terminal, and shielding at least partially encompassing the differential input line. The shielding is connected to a node of the differential input stage of the amplifier.
