state-of-the-art clock driver configurable for improved energy efficiency of a resonant clock

摘要

systems and methods are directed to a configurable last level driver (202) coupled to an inductor-capacitor tank (lc) (204) or a resonant clock to enhance the energy efficiency of the resonant clock. In a warm-up stage, the last level clock driver can be enabled to store energy in the lc tank, and in a gating stage, the last level clock driver can be fully or partially disabled. that the energy stored in tank lc can be recirculated within a clock distribution network. At a renewal stage, the last level clock driver can be enabled to reset the energy lost by the lc tank in power recirculation within the clock distribution network during the on / off stage. Programmable counters (222, 226, 230) can be used to control the durations (224, 228, 232) of the heating, on / off, and renewal stages.
