摘要
An integrated circuit includes inter-digital transducers in a silicon die, where the inter-digital transducers are driven to excite phonons in the silicon die to modulate its thermal conductivity. The thermal conductivity may be increased by exciting acoustic phonons in the silicon die, so that heat dissipation is improved, or the thermal conductivity may be decreased by exciting optical phonons so that heat dissipation is reduced. In conjunction with power management, the thermal conductivity is increased or decreased depending upon the power states of various functional units in the silicon die and depending upon various temperature sensors.
