摘要： A power supply that provides a supply voltage to an integrated circuit (IC) includes high and low power regulators and a power management circuit. The high power regulator regulates the supply voltage at a first voltage level and the low power regulator is set to an inactive mode when the IC is in a RUN mode. When the IC transitions from the RUN mode to a STOP mode, the high power regulator stops regulating and the supply voltage is maintained at a second voltage level, while the lower power regulator is set to an active mode for regulating the supply voltage at a third voltage level. A fallback signal is generated when the supply voltage drops below a first threshold value after which the low power regulator is set in the inactive mode and the high power regulator is configured to regulate the supply voltage at a fourth voltage level.

摘要： In an integrated circuit, a clock monitor circuit detects when an analog clock signal output by an on-chip crystal oscillator has stabilized. The clock monitor circuit uses an envelope follower circuit to monitor the envelope of the analog clock signal and compare the amplitude of the envelope with a predetermined amplitude value. When the predetermined value is reached and the envelope has remained steady for a predetermined time, an oscillator okay signal is generated. If an oscillator okay signal is not detected within another predetermined time, then an oscillator failure signal may be generated.

摘要： A voltage switching system for an integrated circuit (IC) operable in first and second operational modes includes a handover module, first and second voltage regulators, a switch driver, a transistor, and a comparator. When the IC transitions between modes, the handover module receives ramp control and hand-over start signals, generates comparator and bandwidth control signals based on the hand-over start signal and a ramp signal based on the ramp control signal. The switch driver generates a power control signal based on the comparator control signal and a gate input signal based on the ramp signal. The comparator compares first and second voltage signals based on the power control signal and generates a hand-over complete signal. The handover module generates a final hand-over complete signal based on the hand-over complete signal, indicative of completion of transition between the first and second operational modes.
