摘要： An integrated circuit (IC) with voltage regulation includes high power and low power domains, low and high voltage regulators and a low power regulator. The low voltage regulator powers the high and low power domains when the IC is in a HIGH power mode. The low power regulator receives a voltage from a high voltage regulator and powers the low power domain when the IC is in a LOW power mode. The IC includes a switching module that disconnects the low voltage regulator from the low power domain when the output voltage of the high voltage regulator is lower than a threshold voltage during power-up and connects the low voltage regulator to the low power domain when the voltage regulated by the high voltage regulator exceeds the threshold voltage.

摘要： An integrated circuit (IC) includes a digital-to-analog converter (DAC), a voltage monitoring circuit, and a controller. The voltage monitoring circuit includes low voltage detect (LVD) and low voltage warning (LVW) circuits that generate LVD and LVW reference voltage signals. The controller generates and stores a voltage margin word (a difference between first and second DAC words that correspond to the LVD and LVW reference voltage signals, respectively). The controller compares the voltage margin word with predetermined maximum and minimum voltage margin words. If the voltage margin word does not lie between the predetermined maximum and minimum voltage margin words, the controller generates a voltage trimming signal that scales the LVW reference voltage signal. After scaling, if the voltage margin word lies between the predetermined maximum and minimum voltage margin words, the controller generates a calibration pass signal, otherwise the controller generates a calibration fail signal.
