摘要: The first fully integrated GaInP/GaAs heterojunction bipolar transistor (HBT) quadrature voltage controlled oscillator (VCO) using the stacked-transformer LC tank is demonstrated at 5.43-5.31 GHz with low-phase-noise performance. The stacked-transformers are formed by two interconnect metal layers and possess good electrical properties at high frequencies because of the semi-insulating GaAs substrate. The quadrature VCO at 5.38 GHz has phase noise of -127.4 dBc/Hz at 1 MHz offset frequency, output power of -4 dBm and a figure of merit (FOM) -191 dBc/Hz.
