Abstract
A silicon bipolar VCO implementing a double-coupled transformer is disclosed. The VCO circuit, which is suitable in the field of integrated RF circuits, has been integrated into a universal LNB having a down-converter block and PLL merged into a single die and implemented in silicon bipolar technology. The integrated transformer is formed by three turns of stacked metal layers, where the topmost metal layer is employed for the resonator inductance. The VCO is missing conventional biasing resistors and decoupling capacitors, thus improving phase noise and tuning range performance.
