Abstract
A multi-domain RC clamp circuit. A circuit is provided that includes a first power domain having a first RC clamp with a first transistor arranged to bypass a first resistor of the first RC clamp; and a second power domain having a second RC clamp with a second transistor arranged to bypass a second resistor of the second RC clamp, wherein the second transistor is controlled by a first input from the first power domain and the first transistor is controlled by a second input from the second power domain.
