Claim Text:
1. A voltage-controlled oscillator, comprising: an inductor having a tap and having or coupled to a positive-side output node and a negative side output node, wherein the tap is configured to receive a first current; a coarse grain capacitor array coupled to the positive-side output node and the negative side output node and configured to respectively receive select signals; a varactor coupled to the positive-side output node and the negative side output node and configured to receive a control voltage; wherein the varactor includes first MuGFETs; a transconductance cell coupled to the positive-side output node and the negative side output node and having a common node; and a frequency scaled resistor network coupled to the common node and configured to receive the select signals for a resistance for a path for a second current; wherein:
