Physically obfuscated circuit

A physically obfuscated circuit (POC) circuit including a plurality of subcircuits, each comprising at least one p-channel field effect transistor (FET) and at least one n-channel FET, connected such that the at least one n-channel FET, if supplied with an upper supply potential at its gate, supplie...

Summary:A physically obfuscated circuit (POC) circuit including a plurality of subcircuits, each comprising at least one p-channel field effect transistor (FET) and at least one n-channel FET, connected such that the at least one n-channel FET, if supplied with an upper supply potential at its gate, supplies a lower supply potential to the gate of the at least one p-channel FET and the at least one p-channel FET, if supplied with the lower supply potential at its gate, supplies the upper supply potential to the gate of the at least one n-channel FET.
