In this paper, a 5 GHz low-phase noise RF CMOS quadrature voltage controlled oscillator (QVCO) is presented. The quadrature signals are generated by coupling two VCOs through pMOS coupling transistors. The tail biasing MOS current mirror is replaced with tail biasing resistor of 100 Ω, multifingers...
