Abstract
A voltage regulator includes an amplifier, an output stage coupled with the amplifier, at least one back-bias circuit, and an output end coupled with the output stage and with the amplifier. The output stage includes at least one transistor having a bulk and a drain. The at least one back-bias circuit is coupled with the bulk of the at least one transistor. The output end is configured to be coupled with a memory array and with an output end of another voltage regulator. The back-bias circuit is configured to reduce a contention current between the voltage regulator and the other voltage regulator during a standby mode.
