Abstract

A fully-monolithic 3-element array of coupled voltage-controlled-oscillator (VCO) network was fabricated in a 0.18μm SiGe BiCMOS process for potential use in a Rx/Tx modules. A digitally controlled on-chip passive network was designed and used for controlling the coupling strength across the array VCO units. The operational bandwidth of this core network resides in the S-Band from 1.2GHz to 1.7GHz. The integrated VCO network can be injection-locked via an external RF source to achieve excellent phase noise performance. These characteristics make this coupled-VCO network a very attractive choice for possible use in phased-array radar applications. The chip's total power consumption is 30mW (12mA at 2.5V).
