Voltage conversion and integrated circuits with stacked voltage domains |
摘要 |
An integrated circuit (IC) system includes a plurality of ICs configured in a stacked voltage domain arrangement such that a low side supply rail of at least one of ICs is common with a high side supply rail of at least another of the ICs; a reversible voltage converter coupled to power rails of each of the plurality of ICs, the reversible voltage converter configured for stabilizing individual voltage domains corresponding to each IC; and one or more data voltage level shifters configured to facilitate data communication between ICs operating in different voltage domains, wherein an input signal of a given logic state corresponding to one voltage in a first voltage domain is shifted to an output signal of the same logic state at another voltage in a second voltage domain. |
