Abstract:
This article presents a frequency synthesizer for generating quadrature local-oscillator (LO) waveforms covering an octave range of 6 to 12-GHz. It uses two voltage-controlled oscillators (VCO) to cover an octave range from 12 to 24 GHz. The VCOs employ inductor mode switching in addition to conventional capacitor switching to obtain a wide tuning …
