  • System and method for reducing current noise in a VCO and buffer
    Patent number: 11290058
    Abstract: A voltage controlled oscillator (VCO) and buffer circuit includes a voltage controlled oscillator (VCO), a buffer circuit configured to receive a signal generated by the VCO, the buffer circuit comprising a first transistor having a parasitic gate-source capacitance (Cgs), and a second transistor coupled across the first transistor, wherein a gate of the first transistor is coupled to a drain and a source of the second transistor, and a gate of the second transistor is coupled to a source of the first transistor.
    Type: Grant
    Filed: October 22, 2020
    Date of Patent: March 29, 2022
    Assignee: QUALCOMM Incorporated
    Inventors: Yue Chao, Yinghan Wang, Marco Zanuso, Rajagopalan Rangarajan
