  • Abstract This thesis describes the design and implementation of the front-end circuit of a 2.4/5.2 GHz dualband receiver. The circuit blocks include a gain-controllable concurrent dualband LNA, a mixer and a VCO using TSMC 0.18μm 1P6M CMOS process. Because the dualband receiver receives the two desire signals simultenously, a concurrent dualband LNA is adopted. The proposed LNA is single-ended, and it needs an active balun to connect the LNA to active double-balanced mixer. The designed VCO oscilating at 3.7 GHz, makes the RF signals for 2.4GHz and 5.2GHz downconvert to the first IF of 1.3GHz and 1.5GHz, respectively. For the 2.4GHz band, the front-end circuit for the receiver provides overall gain of 28.5dB and noise figure of 4.8dB. For the 5.2GHz band, the overall gain of the receiver is 31dB, and the overall noise figure is 4.5dB. The phase noise of dualband receiver is 117dBc/Hz@1MHz, and the total power dissipation is 55.4mW.
