Abstract
A level translator has a pair of transistors, wherein a first transistor of the pair of transistors and a second transistor of the pair of transistors are complimentary. A pair of capacitors are provided, wherein a first capacitor of the pair of capacitors is coupled to a voltage input VIN and to a gate of a first transistor of the pair of complimentary transistors and a second capacitor of the pair of capacitors is coupled the voltage input VIN and to a gate of a second transistor of the pair of complimentary transistors. A flip flop device is provided having a first input coupled to a drain of the first transistor, and a second input coupled to a drain of the second transistor. A pair of resistors is provided, wherein a first resistor of the pair of resistors is coupled to the gate of the first transistor and to a voltage supply of VDD, and a second resistor of the pair of resistors is coupled to the gate of the second transistor and to a voltage supply VSS. A pair of clamping circuits is provided, wherein a first clamping circuit of the pair of clamping circuits is coupled to the gate of the first transistor and to a voltage supply of VDD, and a second clamping circuit of the pair of clamping circuits is coupled to the gate of the second transistor and to a voltage supply VSS.
