Abstract:
1. A dynamic voltage scaling system having time borrowing and local boosting capability, including: a time borrowing circuit, connected electrically between a primary stage logic circuit and a secondary stage logic circuit, said time borrowing circuit receives an all-domain clock signal, and generates an output data to said secondary stage logic circuit based on input data of said primary stage logic circuit; and a local boost circuit, connected electrically to said time borrowing circuit and said secondary stage logic circuit, and is connected to a low working voltage line, wherein, when said input data lags behind a positive level of said all-domain clock signal, said time borrowing circuit changes its state to produce a warning signal, so that said local boost circuit disconnects its connection to said low working voltage line based on said warning signal, and then is connected electrically to a high working voltage line.
