Summary:
A fully-monolithic 3-element 1-Dimensional (1-D) array of bilaterally coupled voltagecontrolled-oscillator (VCO) network was designed and fabricated in a 0.18μm SiGe BiCMOS process. Each VCO unit cell consists of a cross-coupled differential pair with on-chip inductors and varactors and oscillates at around 1.5GHz. A digitally controlled on-chip resistors network was designed and used for controlling the bilateral coupling strength across the array VCO units. The integrated coupled VCO array can be injectionlocked via an external RF source to achieve excellent phase noise performance. These characteristics make this coupled-VCO network an attractive choice for possible use in phased-array applications.
