Facilitating powering up/down respective analog circuits of mixed-signal devices utilizing a reconfigurable power sequencer component and corresponding reconfigurable sequencer processing unit(s) is presented herein. A system can comprise a mixed-signal component comprising a group of analog circuits comprising respective inputs to facilitate a power-up and a power-down of respective portions of the analog circuits; and a reconfigurable power sequencer component that obtains, from a reconfigurable memory of the system, reprogrammable information representing respective timed sequences of digital outputs electronically coupled to the respective inputs of the group of analog circuits, and based on the reprogrammable information, generates the respective timed sequences of the digital outputs to facilitate the power-up and the power-down of the respective portions of the analog circuits.

Reconfigurable power sequencer for embedded sensors and mixed signal devices

To limit motion in an electromechanical system, an input signal is filtered using an adaptive filter, such as an infinite impulse response filter, to yield a predicted motion, and the input signal is attenuated by an amount controlled by the predicted motion. The filtering may further yield a predicted temperature, and the amount of attenuating may be further controlled by that temperature. Components of the input signal at selected frequencies may be removed, and a portion of the input signal from which the components have been removed may be mixed with a portion of the input signal from which components have not been removed. The removing of components at selected frequencies may include applying a notch filter, and the two portions may be equalized. phase-adjusting the unfiltered portion to account for phase delay introduced by the notch filter. The notch filter may operate at a resonant frequency of the system.
