Abstract :
This paper presents the design of differential and phase-tunable quadrature K-band digitally-controlled oscillators (DCOs) utilizing a tunable-dielectric resonator structure, and preliminary measured results for the differential DCO. The prototype differential oscillator exhibits ~1 GHz of tuning range with eight digitally controlled states. The quadrature oscillator design has 256-state (8-bit) frequency control and a simulated phase tuning authority of > 30 degrees to correct for wide process and operating temperature variability.
