Abstract
A circuit arrangement is provided comprising a first partial circuit to receive a supply voltage, a second partial circuit to receive an output signal of the first partial circuit and a first clock signal, the second partial circuit to store the output signal of the first partial circuit depending on the first clock signal, and a control unit to decouple the supply voltage from the first partial circuit for a time period that is shorter than a cycle duration of the first clock signal, wherein the control unit is configured to receive a second clock signal which is derived from the first clock signal by delaying.

Circuit arrangement comprising:
- a first partial circuit to receive a supply voltage;
- a second partial circuit to receive an output signal of the first partial circuit and a first clock signal, the second partial circuit to store the output signal of the first partial circuit depending on the first clock signal;
- and
- a control unit to decouple the supply voltage from the first partial circuit for a time period that is shorter than a cycle duration of the first clock signal,
- wherein the control unit is configured to receive a second clock signal,
- wherein the first clock signal is a delayed second clock signal, and
- wherein the control unit is configured to couple the supply voltage with the first partial circuit at least between an edge of the second clock signal and the delayed edge of the first clock signal.
A method of operating a circuit arrangement, comprising:
- providing an output signal of a first partial circuit to a second partial circuit;
- storing the output signal in the second partial circuit depending on a first clock signal;
- decoupling a supply voltage from the first partial circuit for a time period that is shorter than a cycle duration of the first clock signal;
- providing a second clock signal;
- delaying the second clock signal, the delayed second clock signal being the first clock signal;
- and
- coupling the supply voltage with the first partial circuit at least between an edge of the second clock signal and the delayed edge of the first clock signal.
A system comprising:
- a controller,
- a circuit arrangement having a first partial circuit to receive a supply voltage, a second partial circuit to receive an output signal of the first partial circuit and a first clock signal, the second partial circuit to store the output signal of the first partial circuit depending on the first clock signal, and a control unit to decouple the supply voltage from the first partial circuit for a time period that is shorter than a cycle duration of the first clock signal, wherein the control unit is configured to receive a second clock signal, wherein the first clock signal is a delayed second clock signal, wherein the control unit is configured to couple the supply voltage with the first partial circuit at least between an edge of the second clock signal and the delayed edge of the first clock signal;
- and
- a communication interface in communication with the circuit arrangement to transfer data to the circuit arrangement in accordance with the controller.
