Load-Independent Inverse Class-E Oscillator with Armstrong-Oscillator Based Topology <Abstract> This paper proposes the load-independent inverse class-E oscillator with Armstrong-oscillator based topology. The proposed oscillator achieves constant output voltage and soft switching against load variations due to the load-independent design. Moreover, the proposed circuit realizes the self-tuning function using the Armstrong- oscillator topology. As a result, the oscillator can also have robustness against the variations in the resonant frequency. The experimental results showed the effectiveness of the proposed oscillator. |
