NettetLC VCO is made controllable by changing the control bits BI<2:0> in the Fig. 3. This control bit is powered down M0-2 by controlling SW1, and the transconductance of the transistor M3-8 is also controlled. To keep the VCO gain constant, varactor finger number can be controlled depending on the oscillation frequency with BV<2:1> bits. NettetThis paper describes a new approach to low-phase-noise LC VCO design based on transconductance linearization of the active devices. A prototype 25 GHz VCO based on this linearization approach is integrated in a dual-path PLL and achieves superior performance compared to the state of the art.

NettetThe present invention provides a linearized and delay compensated all CMOS voltage controlled oscillator. A transconductance converter receives a control voltage input and provides a control current to a current controlled ramping circuit that is responsible for providing two ramping voltage outputs to the positive inputs of two comparators. This paper presents a wide-range and low phase noise mm-Wave Voltage Controlled Oscillator (VCO) based on the transconductance linearization technique. The proposed technique eliminates the deep triode region of the active part of the VCO, and lowers the noise introduced by the gm-cell.
