Abstract:
A quadrature oscillator includes a first oscillator having a first second-order harmonic node, a second oscillator having a second second-order harmonic node, and at least one capacitor coupling the first second-order harmonic node and the second second-order harmonic node. The first oscillator is configured to supply an in-phase signal and the second oscillator is configured to supply a quadrature signal.
