摘要： Embodiments of the present invention provide a design structure and method for compensating for a change in frequency of oscillation (FOO) of an LC-tank VCO that includes a first node; second node; inductor; first capacitive network (FCN) that allows the design structure to obtain a target FOO; compensating capacitive (CCN) network that compensates for a change in the design structure's FOO; second capacitive network (SCN) that allows the design structure to obtain a desired FOO; a filter that supplies a voltage to the SCN and is coupled to the SCN; a transconductor that compensates for a change in the design structure's FOO; and a sub-circuit coupled to the SCN that generates and supplies voltage to the CCN sufficient to allow the CCN to compensate for a reduction in the design structure's FOO. The first and second nodes are coupled to the inductor, FCN, CCN, SCN, and sub-circuit.

摘要： An approach for a transconductance cell for use in a voltage controlled oscillator (VCO) is provided. The transconductance cell includes a first NFET stack connected in series to a first PFET stack. The transconductance cell includes a second NFET stack connected in series to a second PFET stack. The first NFET stack and the first PFET stack are cross-coupled to the second NFET stack and the second PFET stack. The first NFET stack and the second NFET stack are connected to a tail node. The first PFET stack and the second PFET stack are connected to a power supply node.
