  • Circuit for compensating an offset voltage in an amplifier
    Patent number: 10408861
    Abstract: A circuit for compensating an offset voltage in an amplifier or a DC component in a signal supplied to the amplifier comprises the amplifier and a first voltage source. The amplifier has at least one measurement signal port and at least two contacts for a supply voltage. Each of two contacts is connected to a different terminal of the first voltage source. The potential at each contact is separated from a ground potential and from an external supply potential.
