Abstract

Barium Strontium Titanate (BST) has a fielddependent permittivity and can be used as a dielectric in voltage tunable capacitors or varactors. These BST-based varactors are passive devices and have significantly different properties compared to semiconductor varactors. A voltage tunable oscillator using a BST thin film varactor was designed and characterized. The frequency of oscillation varied from 34.8MHz to 44.5 MHz (28% tuning) upon application of 7 volts tuning voltage. The VCO gain was 1.38MHz/V and the 2 nd harmonic was over 23dB below the fundamental throughout the tuning range.
