  • Publication number: 20240305288
    Abstract: A stack of transistors having equal voltage division when in the OFF state is disclosed. Rather than utilizing compensation capacitors, the present system varies the gate periphery of the transistors in the stack to achieve the desired voltage division. This may be done by varying the number of gate fingers in each transistor, by varying the gate width of the transistors or a combination of these approaches. This approach results in easier design, routing and simulation, with improved power handling.

  • Patent number: 5083098
    Abstract: A voltage controlled oscillator having an active network and a tuning network that includes a transmission line impedance transformer having a first end coupled to an output circuit of the VCO, and having a selectable effective width that determines the tuning bandwidth of the oscillator. A varactor diode is coupled to the second end of the transformer line, and a bias line is coupled between a tuning port and the varactor diode. The transmission line impedance transformer more particularly includes a main transformer line, a plurality of transmission lines adjacent the main transformer line, and wire bonds for electrically connecting selected ones of the plurality of lines to the main transformer line, whereby connection of selected ones of the transmission lines to the main transformer line increases the effective width of the impedance transformer.
