Patent ID: 8558520

Claim:
An electrical circuit for manipulating at least one of a voltage and a current on a bus wire, wherein the circuit comprises: a first switch having a first gate, a first source, and a first potential reduction unit, wherein the manipulating of the at least one of a voltage and a current on the bus wire is controllable by a change of a gate voltage at the first gate, wherein the first potential reduction unit is suitable for lowering a potential difference between the first gate and the first source of the first switch, wherein the lowering of the potential difference is causable by turning an output of a first control voltage source into an high-impedance state; and a second switch having a second gate, a second source, and a second potential reduction unit, wherein the second potential reduction unit is suitable for lowering a potential difference between the second gate and the second source of the second switch, wherein the lowering of the potential difference is caused by a shutting-off of a second control voltage.
