Abstract: A chip includes a merger cell including a first p-type length of diffusion (LOD) region extending in a first direction, a first n-well underneath the first p-type LOD region, a first supply rail configured to receive a first supply voltage, and a first n-tap coupling the first n-well to the first supply rail. The merger cell also includes a second p-type length of diffusion (LOD) region extending in the first direction, a second n-well underneath the second p-type LOD region, a second supply rail configured to receive a second supply voltage different from the first supply voltage, and a second n-tap coupling the second n-well to the second supply rail.

Abstract: A system includes a first park circuit having a signal input, an output, and a control input. The system also includes a first signal path having an input and an output, wherein the input of the first signal path is coupled to the output of the first park circuit. The system also includes a second park circuit having a signal input, an output, and a control input, wherein the signal input of the second park circuit is coupled to the output of the first signal path. The system further includes a second signal path having an input and an output, wherein the input of the second signal path is coupled to the output of the second park circuit.
