Abstract
A synchronizing flip-flop circuit configuration for synchronizing data includes an input and an output of the synchronizing flip-flop circuit configuration. A first transfer gate, connected to the input of the synchronizing flip-flop circuit configuration, is controlled by a first clock signal. A second transfer gate connected between the first transfer gate and the output of the synchronizing flip-flop circuit configuration is controlled by a second clock signal being inverted with respect to the first clock signal. A first series-connected inverter pair is connected between the first transfer gate and the output of the synchronizing flip-flop circuit configuration. At least one second inverter series-connected inverter pair is connected in series with the first inverter configuration between the first transfer gate and the output of the synchronizing flip-flop circuit configuration, thereby preventing occurrence of meta-stable conditions between data to be synchronized.
