RF Front-end Integrated Circuits with 2.4 GHz Antenna for Wireless Communication Receiver

The proposed integrated CMOS front-end chip design, intended for use in 2.4 GHz radio frequency front-end receiver, has been implemented in tsmc 0.18um CMOS processing. The 2.4 GHz receiver front-end design consists of image reject low noise amplifier (LNA), the 3
^rd
order passive bandpass Gm-C loop filter, gilbert cell double balance mixer with passive balun and switched capacitor tuning voltage-controlled oscillator (VCO). The proposed 2.4 GHz antenna applying for 2.4 GHz RF front-end receiver application is presented and enhance performance in this article design. Experimental results of the RF integrated 2.4 GHz RF frontend receiver exhibit radiation pattern with the proposed 2.4 GHz to 2.5 GHz antenna at anechoic chamber room.
