A circuit is configured to generate periodic control signals including at least two mutually phase-shifted control signals. The circuit includes a plurality of generator circuits, where a separate generator circuit is provided for each control signal output by the circuit. Each generator circuit includes a phase value memory configured to store a phase value, where the phase value defines a phase shift. Each generator circuit includes an activation input and, in response to application of an activation level to the activation input, is configured to initiate a generation of a control signal which is phase-shifted by an amount defined by the phase value. The activation inputs of the generator circuits are connected together to an activation circuit for outputting an activation level to the generator circuits simultaneously.
