1. An oscillator network comprising:

  • at least one oscillator network output;

    a first tank circuit;

    at least one additional tank circuit;

    whereineach tank circuit comprisesa first and second output,a plurality of coils each having a first and second lead,at least one coil encompassing a first surface different from a second surface encompassed by the remaining coils,the first and second leads of the plurality of coils directly connected respectively to the first and second outputs,at least two transistors of one conductivity type cross coupled to each other, andat least one capacitor; and

    at least one coil in the first tank circuit having a flux linkage to at least one coil in the additional tank circuit, whereinat least one of the coils in the first tank circuit overlaps and shares a common encompassed surface on a first substrate with at least one of the coils in one of the additional tank circuits.
