Abstract
An integrated level shifting combinatorial circuit receives a plurality of input signals in a first voltage domain and performs a combinatorial operation to generate an output signal in a second voltage domain. The circuit includes combinatorial circuitry includes first and second combinatorial circuit portions operating in respective first and second voltage domains. The second combinatorial circuit portion has an output node whose voltage level identifies a value of the output signal and includes feedback circuitry which applies a level shifting function to an intermediate signal generated by the first combinatorial circuit portion. A contention mitigation circuitry reduces a voltage drop across at least one component within the feedback circuitry in situations when the combinatorial circuitry's performance of the combinatorial operation causes the combinatorial circuitry to switch the voltage on the output node, the contention mitigation circuitry thereby assists the combinatorial circuitry in the output node voltage switching.
