Circuit for compensating an offset voltage in an amplifier |
| 摘要 |
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. |

1. A circuit for compensating an offset voltage in an amplifier or a DC component of a signal supplied to the amplifier,
wherein the circuit comprises the amplifier and a first voltage source, wherein the amplifier has at least one measurement signal port and at least two power supply contacts for a supply voltage, wherein each of two contacts is connected to a different terminal of the first voltage source, and wherein each power supply contact of the amplifier is separated from a ground potential. |
