Abstract: Aspects of the disclosure provide method and apparatus for detecting attributes of an input power supply. The method includes receiving a first signal generated based on a second signal that is predictive. The first signal includes a portion that substantially corresponds to the second signal. Further, the method includes detecting attributes of the portion of the first signal that substantially corresponds to the second signal, and determining attributes of the second signal based on the attributes of the portion of the first signal that substantially corresponds to the second signal.

Abstract: Methods and systems for converting analog signals to digital signal using a cyclic analog-to-digital converter are disclosed. For example, such a cyclic analog-to-digital converter may include digitization circuitry configured to digitize either an input signal or an amplified feedback residue signal to produce first digital signals, digital accumulator circuitry configured to produce N-bits of digital information based on the first digital signals over N consecutive cycles, where N is a positive integer, and a residue amplifier configured to amplify a residue signal to produce the amplified feedback residue signal, wherein for at least M cycles, the residue amplifier operates using a capacitor averaging technique, where M is a positive integer and less than N, and wherein for P cycles the residue amplifier operates using a simple gain amplification technique, where P is a positive integer and less than N.

Abstract: In one embodiment, an apparatus includes a transistor having a gate, a drain, and a source. The drain is coupled to receive an AC power supply signal. A component is coupled between an output node and the gate of the transistor. The component couples an output voltage from the output node to charge a gate-source capacitor during a first portion of the AC power supply signal. The transistor is configured to turn on during a second portion of the AC power supply signal to send a charge to the output node where the charge is used to power a circuit of a power supply.
