Abstract
A logic circuit comprises a dual rail drive circuit having a first rail and a second rail. The logic circuit further comprises a logic block having a first input coupled to receive an input signal from the first rail of the dual rail driver, and a second input coupled to receive an input signal from the second rail of the dual rail driver. In one embodiment, the input signal from the first rail of the dual rail driver can swing to a voltage level sufficient to turn on a p-channel transistor, and the input signal from the second rail of the dual rail driver can swing to a voltage level sufficient to turn on an n-channel transistor. For example, for a 0.18 micron process the input signal from the first rail may have a voltage swing from VDD to VDD-400 MV, and the input signal from the second rail may a voltage swing from GROUND to 400 MV.
