  • 5G MMWAVE POWER AMPLIFIER CONTROL CIRCUITRY
    Publication number: 20240322766
    Abstract: This application relates to an amplification circuit comprising: a power amplifier stage configured to receive a supply voltage and an RF signal to be amplified; a biasing circuit configured to receive an envelope signal produced from the RF signal and input a bias signal into the power amplifier, said bias signal varying based on the envelope signal such that the bias signal dynamically modulates an output impedance of the power amplifier based on the envelope signal; and an output stage configured to output an amplified RF signal generated by the power amplifier.

  • Slewing mitigation apparatus for switched capacitor circuit
    Patent number: 11595009
    Abstract: A slewing mitigation technique is presented where just the right amount of charge is provided at the switching instant to a switch capacitor circuit so that operational transconductance amplifier (OTA) does not need to provide high peak current. This eliminates slewing altogether and allows using OTAs with less static current for the same settling accuracy.
    Type: Grant
    Filed: July 29, 2021
    Date of Patent: February 28, 2023
    Assignee: Oregon State University
    Inventors: Manjunath Kareppagoudr, Gabor Temes, Jyotindra Shakya, Emanuel Caceres
