Low swing flip-flop with reduced leakage slave latch

A method comprising:

• receiving, at a master latch of a flip-flop, a master latch output signal at a slave latch of the flip-flop, wherein the master latch is coupled to a first power distribution network that provides a first voltage level;
• receiving, at a first latch inverter of a feedback loop of the slave latch, the master latch output signal, wherein the first latch inverter is coupled to a second power distribution network that provides a second voltage level wherein, relative to a reference voltage level, the second voltage level is less than the first voltage level;
• providing, from the first latch inverter, a first latch inverter output signal that is driven by the second power distribution network;
• and
• providing a slave latch output signal, based on a first latch inverter output signal, that is driven by the first power distribution network.

A flip-flop comprising:

• a master latch comprising:
• a power node connected to a first power distribution network;
• an input node to receive a data signal to be latched;
• and
• an output node to provide a master latch output signal that is driven by the first power distribution network;
• and
• a slave latch comprising:
• a first power node connected to the first power distribution network;
• a second power node connected to a second power distribution network, wherein, relative to a reference voltage level, the second voltage level is less than the first voltage level;
• an input node coupled to the output of the master latch;
• an output node to provide a slave latch output signal that is driven by the first power distribution network;
• and
• a feedback circuit comprising a slave latch inverter connected to the second power node of the slave latch, including an input terminal coupled to the output of the master latch, and an output terminal to provide a slave latch inverter output signal that is driven by the second power distribution network.
