Abstract
A quadrature oscillator according to the embodiments herein comprising two pairs of main transistors, two pairs of resonators and two pairs of injection transistors. The quadrature oscillator is split into two halves, which are separated in the chip layout. That is the two pairs of resonators are separated from each other, and the two pairs of the main transistors are separated from the resonator they coupled to such that the quadrature oscillator is separated into two spaced apart oscillator halves connected by transmission lines.
