Abstract
Multi-Threshold CMOS (MTCMOS) devices include a high threshold voltage current control switch that is responsive to a first control signal, a low threshold voltage logic circuit and a flip-flop that is configured to store data from the low threshold voltage logic circuit and that is responsive to a second control signal. A control circuit also is provided that is configured to change a logic state of the second control signal and then, after a first delay, to change a logic state of the first control signal, in response to the MTCMOS device entering a sleep mode. The control circuit is further configured to change the logic state of the first control signal and then, after a second delay that is different from the first delay, to change the logic state of the second control signal in response to the MTCMOS device entering an active mode. Related methods also are provided.
