Abstract: An electronic device comprises a regulator, and an oscillator and a resistor coupled to the regulator. The electronic device further comprises a feedback controller that includes a differential amplifier coupled between the oscillator, the resistor, and the regulator. The feedback controller is configured to apply a control voltage to the regulator in response to a resistor voltage upon the resistor and an oscillator voltage upon the oscillator. The feedback controller can be coupled to control a substantially equal voltage upon the resistor and the oscillator.

Abstract: A method of operating a power up circuit is disclosed. The method includes receiving an input voltage and creating a plurality of sample voltages from the input voltage. One of the sample voltages is selected and compared to a reference voltage. The power up circuit produces a brown-out signal in response to the step of comparing.

Abstract: Digital control of a crystal oscillator is implemented in a manner that allows frequency accuracy to be traded off dynamically with power consumption. The oscillator transitions between a less accurate/lower power mode and a high accuracy/higher power mode smoothly without requiring any external clock source during the transition. Power consumption is optimized because the crystal oscillator provides the clock source during transitions between the power modes and no other clock source is needed for these transitions. The system can also optimize the startup time and steady state power consumption independently.

Abstract: A circuit includes a ring oscillator that includes a plurality of delay stages coupled in series to generate an output frequency for the ring oscillator. A capacitive array is operatively coupled between a supply rail and a power rail for each of the delay stages to supply power to the delay stages. The capacitive array selectively adjusts the output frequency of the ring oscillator via a capacitive setting of the capacitive array.

Abstract: A system includes a multiplexer, an input/output (I/O) pin, a logic circuit, and a control register. The multiplexer has multiple inputs, an output, and a selection input. The logic circuit is coupled between the multiplexer and the I/O pin. The logic circuit has a first input. The control register includes first and second bit fields corresponding to the I/O pin. The first bit field is coupled to the selection input of the multiplexer, and the second bit field is coupled to the first input of the logic circuit.

Abstract: One example relates to a monitoring circuit that includes a capacitive digital-to-analog converter that receives a binary code, a reference voltage, a monitored voltage, and a ground reference, the capacitive digital-to-analog converter outputting an analog signal based on the binary code, the reference voltage, the monitored voltage, and the ground reference. The monitoring circuit further includes a comparator including a first input coupled to receive the analog signal and a second input coupled to the reference voltage, the comparator comparing the analog signal to the reference voltage and outputting a comparator signal based on the comparison. The monitoring circuit yet further includes a binary code generator that generates the binary code based on the comparator signal, the binary code approximating a magnitude of the monitored voltage.
