Abstract
This paper proposes two schemes for the low-voltage swing clocks in global and local clock distributions. These schemes provide about 50% total clocking power reduction or about 25%, full-chip power reduction in a microprocessor case. The circuit structures and operation principles for low-and-high swing voltage conversions are presented. It also includes a latch with four clock lines in half-Vdd swings. A USA patent has been granted for the proposed schemes
