An integrated circuit (IC) can include multiple power domains that are served by a common power source. In an example, a first IC power rail can be coupled to the source and a first consumer circuit. A second IC power rail can be coupled to a second consumer circuit. The second IC power rail can receive a filtered power signal from an isolation module that is coupled between the first and second power rails. In an example, an isolation module includes an integrated inductor and a capacitor (e.g., a land-side capacitor). The integrated inductor can optionally include multiple spaced apart conductive layers that are electrically coupled. The integrated inductor can optionally include a series of conductive traces and plated through holes or vias that together provide a current path with multiple turns.

Isolation module for use between power rails in an integrated circuit

Methods and apparatus relating to a programmable scalable voltage translator are described. In one embodiment, logic translates an input voltage level into a plurality of output voltage levels during a low power consumption state of a device. Other embodiments are also disclosed and claimed.

Programmable scalable voltage translator

A device, computer system, and method are disclosed. In one embodiment, the device includes a memory buffer driver circuit that can drive signals on a memory channel at a given voltage level. The voltage at the voltage level is supplied to the memory buffer driver circuit from a rail of a power delivery network. The voltage level exhibits a repeatable fluctuation cycle at a resonant frequency of the power delivery network. The device also includes an on-die termination logic circuit that asserts a first termination resistance on the memory channel after the memory channel enters an idle state but before the voltage level reaches a peak of the repeatable fluctuation cycle. The on-die termination logic circuit then deasserts the first termination resistance on the memory channel at a later point in time.
