A frequency selectable driver circuit (driver circuit) includes a current drive transistor between a first and second node for driving a frequency selectable oscillator (FSO) coupled therebetween that includes a first LC network including an inductor L2 and a capacitor C2 in series and a second LC network in series with the first LC network. The second LC network includes a capacitor bank including capacitors in parallel including switches for switching (selectable capacitors) and an inductor L3 in parallel to the capacitor bank. Values of L2 and C2 provide a low frequency point fL which the LC network is overall capacitive, and in a frequency range between fa and fb above fL with only a portion of selectable capacitors selected a capacitance of the capacitor bank and value of L3 results in an overall impedance for the second LC network that is capacitive between fa and fb and inductive elsewhere.
