Abstract
A 61% DC- to-RF conversion efficiency oscillator with very low bias of 2.0 V is designed in 1.86 GHz. To obtain maximum DC-to-RF conversion efficiency, DC operating point is chosen in class AB with the second harmonic loading. The maximum efficiency and output power are analyzed and predicted very fast through a novel HTSM (Harmonic Two Signal Method) under class AB or B bias condition. Harmonic components effects on the oscillators, self-oscillating condition, and DC current change as the RF drive level are also analyzed through HTSM.
