Abstract :
A fully integrated CMOS receiver consisting of an LNA and a mixer has been designed and fabricated in IBM BiCMOS 7WL 180 nm technology. An on-chip balun loading the second stage of the LNA was implemented as well for single-to-differential conversion. The receiver was developed for high performance wireless local positioning systems and excellent experimental results were demonstrated: a conversion gain (CG) of 28 dB, a low noise figure (NF) value of 3.3 dB and an input third order intercept point (IIP3) of - 11.5 dBm while consuming only 50 mW. The low noise, high gain and very high linearity performance of the proposed receiver topology makes it to be an optimum choice for the targeted local positioning application based on frequency modulated continuous wave (FMCW) radar.
