Patent number: 7793130Abstract: System and method for providing power to integrated circuitry with good power-on responsive time and reduced power-on transient glitches. A preferred embodiment comprises a daughter switch coupled to a circuit block, a first control circuit coupled to the daughter circuit, a second control circuit coupled to the first control circuit, and a mother circuit coupled to the circuit block and to the second control circuit. After the daughter switch is turned on by a control signal, the mother switch is not turned on until the daughter switch has discharged (charged) the voltage potential across power rails of the mother circuit to a point where glitches are minimized. The second control circuit turns on the mother circuit when the reduced voltage potential is reached, with a signal produced by the first control circuit reflects the voltage potential. Furthermore, a bypass circuit can be used to reduce leakage current.Type: GrantFiled: April 24, 2007Date of Patent: September 7, 2010Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Shih-Hsien Yang, Chung-Hsing Wang, Lee-Chung Lu, Chun-Hui Tai, Cliff Hou
