RECYCLING CHARGE TO REDUCE ENERGY CONSUMPTION DURING MODE TRANSITION IN MULTITHRESHOLD COMPLEMENTARY METAL-OXIDE-SEMICONDUCTORMTCMOS CIRCUITS

摘要

In one embodiment, the circuit includes a first circuit block connected to ground via a first sleep transistor, a virtual ground node between the first circuit block and the first sleep transistor, via a second sleep transistor power and a second circuit block which is connected to, and a virtual supply node between the second circuit block and the second sleep transistor. Said circuit further transmission gate (TG), or to enable a charge play between the first circuit block and the second circuit block during the transition to the sleep mode from the active mode to connect the virtual ground node to the virtual supply node and a pass transistor.
