REAL TIME CLOCK (RTC) VOLTAGE REGULATOR AND METHOD OF REGULATING AN RTC VOLTAGE |
摘要 |
A real time clock (RTC) voltage regulator, a method of regulating an RTC voltage and a power management integrated circuit (PMIC). In one embodiment, an RTC voltage regulator includes a current source configured to provide a first current and a voltage regulator having a common gate amplifier and a power device. The first current is employed to establish a reference voltage for the common gate amplifier and the common gate amplifier is configured to control the power device. The power device is configured to provide an RTC voltage for the common gate amplifier.
