  • Structure for a frequency adaptive level shifter circuit
    Patent number: 8686782
    Abstract: The present invention provides an apparatus and method for a frequency adaptive level shifter circuit. The frequency adaptive level shifter circuit includes a first inverter, a second inverter coupled to the output of the first inverter, a capacitor coupled to the output of the second inverter, and a resistor coupled to the output of the capacitor. The frequency adaptive level shifter circuit further includes a transistor coupled to the output of the resistor, wherein the transistor has a gate connected to a reference voltage, a third inverter coupled to the output of the capacitor, and a fourth inverter coupled to the output of the third inverter and the transistor and outputting the signal.
