A Novel Bulk Acoustic Wave based Super-harmonic Quadrature Voltage Control Oscillator

As the demand for wireless connectivity increases, new power and area efficient solutions will be required to meet the specifications of these systems. Most transceivers require a local oscillator with quadrature(I/Q) phases and the power and noise specifications of this oscillator plays a crucial role in the system performance. Although traditionally these oscillators were designed using on chip LC components, recent advances in manufacturing have opened the possibilities of incorporating Bulk Acoustic Wave(BAW) resonators in the design of such oscillators. In this work, we introduce a novel coupling technique for creating a Quadrature Voltage Controlled Oscillator(QVCO) which leads to a lower phase noise and power consumption compared to other published designs.
