  • DIFFERENTIAL AMPLIFIER COMPENSATION
    Publication number: 20230046993
    Abstract: An amplifier includes a first stage and a second stage. The first stage includes a first output and a second output. The second stage includes an output, a first transistor and a second transistor. The first transistor includes a drain coupled to the first output of the first stage, and a source coupled to the output of the second stage. The second transistor includes a drain coupled to the second output of the first stage, and a gate coupled to the output of the second stage.

  • Isolated capacitive power transfer
    Patent number: 10742134
    Abstract: A method and device for providing isolated power transfer to a low-power load across a capacitor of a series resonance circuit are shown. The method includes comparing an output voltage received via a feedback loop with a desired output voltage. Responsive to determining that the output voltage is not equal to the desired output voltage, the method determines a sub-harmonic order of the resonant frequency of the series resonance circuit to use as a switching frequency and switches the series resonance circuit at substantially the determined subharmonic order of the resonant frequency.
