Abstract
An amplifier circuit that includes a first amplifier that has a first input that receives an input signal, a second input and an output. The amplifier circuit also includes a second amplifier that has a first input that is coupled to the output of said the amplifier and a second input. The circuit further includes a first impedance network Z, a second impedance network Z, a third impedance network Zand a fourth impedance network Z. The first impedance network Zis coupled to a load and the second input of the second amplifier, the second impedance Zis connected the output of the first amplifier and the second input of the first amplifier, the third impedance Zis connected to the output of the first amplifier and the load, the fourth impedance Zis connected the output of the second amplifier and the second input of said first amplifier.
