Integrated Header Switch with Low-Leakage PMOS and High-Leakage NMOS Transistors |
摘要 |
System and method for providing power with a large on-current and small off-current to circuitry in an integrated circuit. A preferred embodiment comprises a switch for providing power to circuits in an integrated circuit made from a PMOS transistor and an NMOS transistor coupled in parallel. Each transistor's gate terminal is coupled to a separate control signal line. The PMOS transistor provides current to the circuits at high voltage supply levels while the NMOS transistor provides current to the circuits at low voltage supply levels, wherein the size of the PMOS and NMOS transistor can be changed during design to meet power requirements. Depending upon power requirements, multiple PMOS and NMOS transistors may be used. The combination of PMOS and NMOS transistors permit the use of limited fabrication processes wherein transistor widths can be limited.
