Abstract:

We introduce a new class-F3,5 oscillator topology that enables quadrature operation by duplicating a conventional class-F3 oscillator core and electro-magnetically coupling the two cores through a pair of additional coils feeding source terminals of the gm transistors. The coupling network enhances the 5th-harmonic component, enabling efficient extraction and quadrature operation …
