Supply voltage generator for a display timing controller with current reuse

摘要

A semiconductor IC including a supply voltage generator, one or more first circuit blocks, and one or more second circuit blocks. The supply voltage generator is configured to generate a first supply voltage and a second supply voltage based on an external supply voltage, and to provide the first supply voltage to a first power bus and the second supply voltage to a second power bus. The first circuit blocks are connected between the first power bus and the second power bus, and the second circuit blocks are connected between the second power bus and ground.
