In one embodiment, an apparatus includes a first electrode, one or more processors, and one or more memory units coupled to the one or more processors. The one or more memory units collectively store logic that is configured to cause the one or more processors to control connections of the first electrode by connecting the first electrode to a first reference voltage, then connecting the first electrode to a second reference voltage lower than the first reference voltage, and then connecting the first electrode to a third reference voltage lower than the first reference voltage and the second reference voltage. The second reference voltage is coupled to a capacitor.

Connecting electrodes to voltages

A microcontroller system includes a higher power reference voltage circuit and a lower power reference voltage circuit configured to draw less power than the higher power reference voltage circuit when enabled. The system includes a power state logic controller configured to enable the lower power reference voltage circuit to provide a first regulated voltage during a power saving mode, and, on exiting the power saving mode, enable the higher power reference voltage circuit to provide a second regulated voltage.

Reference voltage circuits in microcontroller systems

A microcontroller system includes a main voltage regulator and a low power voltage regulator having a static current consumption less than the static current consumption of the main voltage regulator. A power state controller enables the low power voltage regulator during a power saving mode. On exiting the power saving mode, the power state controller enables the main voltage regulator and disables the low power voltage regulator after determining that the main voltage regulator is ready. The switching circuitry can be asynchronous.

Laser drive circuit and use

A device and method for detecting timing of an edge of a signal with respect to a timing of a predefined edge of a periodic signal is provided, wherein the edge defines a state change between a first state and a second state of the signal, and wherein the device can include: a phase-shift element to shift the phase of the signal relative to the phase of the periodic signal by a phase shift value at which the state change can be sensed at a point in time determined by the timing of the predefined edge; and a detection element to detect the timing of the edge relative to the timing of the predefined edge on the basis of the phase shift value. The phase-shift element can be an adjustable delay element for delaying the signal by an adjustable delay value as a phase shift value.
