Techniques for improved tuning control of varactor circuits are disclosed. For example, an apparatus comprises a plurality of varactors for tuning a frequency value. The plurality of varactors comprises approximately sqrt(2N) varactors, where N is a number of tunings steps and the plurality of varactors are respectively sized as 1x, 2x, 3x, 4x, . . . , approximately sqrt(2N)x, and where x is a unit of capacitance. A given one of the N tuning steps may be represented by more than one combination of varactors. This may be referred to as redundant numbering. |
