Abstract:This paper proposes an RF signal generator using a time domain harmonic suppression technique based on Fourier series analysis. The circuit consists of four differential ring voltage control oscillators (VCO's) with phase differences and the pulse signal summing circuit. By summing pulse signals from VCO's with appropriate phase differences determined by Fourier series in time domain, the third and fifth harmonics can be cancelled without filters. To confirm the validity, a prototypal RF signal generator was f… Show more
