Abstract :
A fully monolithic coupled differential Voltage-Controlled-Oscillators (VCOs) network for phased-array applications is presented in this paper. The proposed integrated VCO array, operating at 5.78 GHz is implemented on a 0.25 μm BiCMOS SiGe process and is made of two LC-NMOS differential VCOs coupled through a MOS transistor. At 2.5 V power supply voltage, and a power dissipation of 62.5 mW, the coupled VCO array features a measured best case phase noise of -125.21 dBc/Hz at 1 MHz frequency offset from a 5.78 GHz carrier.
