Abstract

The present application discloses various implementations of a power management unit (PMU) suitable for use in a mobile device. In one exemplary implementation, such a PMU includes a gain control block configured to control an oscillator coupled to the PMU. The gain control block is further configured to control a clock output stage of the PMU. The PMU also includes a signal protection circuit coupled to an input of the gain control block. The signal protection circuit is configured to preserve clock signals produced by the clock output stage during a transition to a standby mode.
