Abstract
An ultra low-power differential varactor-less 10 GHz LC oscillator has been fabricated. The implementation IC technology allows surface-mounting, eliminates substrate losses and has a copper back-end. The quality factor of the used 0.63nH inductor is estimated by measuring the required start-up current of the oscillator. With a supply voltage of 3V, the estimated quality factor is as high as 39 at 10 GHz. At 10 GHz the dissipation of the oscillator core is 420 mW (with 3V supply voltage) and the measured phase noise better than -94.7dBc/Hz at 1 MHz offset of the carrier. By increasing the bias current, the frequency can be tuned from 10.2 GHz to 8.7 GHz, which corresponds to 15.8% tuning range. The highlighted fabrication technology eliminates bond-wires, reduces cross-talk and yields excellent passives.
