This brief presents a dual-core, dual-mode digital-controlled oscillator (DCO) featuring a novel transformer-based resonator that minimizes parasitics in the switch connection lines and enhances the ...

This letter presents a dual-core, wide-tuning, class-C voltage-controlled oscillator (VCO) operating at millimeter-wave (mm-wave) frequencies. Each core contains a 7-bit switched capacitor array and a ...
