  • Current-mirror based level shifter circuit and methods for implementing the same
    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.
