  • Voltage controlled oscillator with common mode adjustment start-up
    Patent number: 9742354
    Abstract: The present disclosure provides methods and apparatus for dynamically adjusting the common mode voltage at the LC tank node and/or the power supply voltage of a VCO with an LC resonator in order to force oscillation start-up by temporarily increasing gain. Methods according to certain preferred embodiments may reduce power consumption and/or overcome threshold voltage limitations and/or increase frequency and frequency tuning range during normal (steady-state) operation.
    Type: Grant
    Filed: November 2, 2016
    Date of Patent: August 22, 2017
    Assignee: Microsemi Solutions (U.S.), Inc.
    Inventors: Hormoz Djahanshahi, Kenneth Allan Townsend
