  • Patent number: 11050424
    Abstract: Methods and apparatus for implementing a current-mirror based level shifter circuit are provided. The current-mirror based level shifter circuit includes a current-mirror circuit, a feedback control circuit, a power down circuit and a plurality of inverter circuits. The apparatus is configured to provide a wide voltage shifting range using the current-mirror based level shifter circuit. The apparatus comprising a feedback loop with two diode connected transistors may provide a constant drivability to the node that drives the output, when a current-mirror circuit is turned-off.

  • Patent number: 10812055
    Abstract: Embodiments herein disclose a flip flop comprising at least one of a slave circuit and a retention circuit receiving an input from a master circuit. The output circuit receives an input (X1) from at least one of the slave circuit and the retention circuit. A first node and a second node in the retention circuit receive a power supply from a global power supply through transistors, when a retention is 0 in the retention circuit, so that the slave circuit retains a current state of the X1 and X2 irrespective of a clock input in the slave circuit, and the output circuit receives the stored state of the retention circuit, when a local power supply is turned ON.
