Abstract
A circuit has a first amplifier having first positive and negative inputs and a second amplifier having second positive and negative inputs. A first unit is connectable to the first and second inputs of the amplifiers and a second unit is connectable to the first and second inputs of the amplifiers. In a first phase, the first unit is connected to the amplifiers, wherein the positive input of the first amplifier is coupled to the positive input of the second amplifier and the negative input of the first amplifier is coupled to the negative input of the second amplifier. In a second phase, the second unit is connected to the amplifiers, wherein the positive input of the first amplifier is coupled to the negative input of the second amplifier and the negative input of the first amplifier is coupled to the positive input of the second amplifier.
