Abstract
A data processing system includes first and second power distribution networks to provide power at first and second voltages, and a flip-flop. The second voltage is less than the first voltage. The flip-flop includes a master latch with a power node connected to the first power distribution network, a data signal input, and an output signal output that is driven at the first voltage, and a slave latch with a power node connected to the first power distribution network, an input coupled to the output of the master latch, a slave latch output signal output that is driven by the first voltage, and a feedback circuit with a first latch inverter having a power node connected to the second voltage, an input coupled to the master latch output, and an output terminal to provide an output signal that is driven by the second voltage.
