In this thesis, we present a 0.6V low-power low noise amplifier (LNA) and voltage-controlled oscillator (VCO) for 802.11a WLAN system (5GHz-WiFi) implemented with a TSMC 1P6M 0.18 m RF CMOS technology. The proposed LNA uses a π-matching network instead of inductor degeneration impedance matching network to reduce the area and to improve the linear range. By employing the current-reused structure and forward body bias technique, the proposed LNA can be operated at a reduced supply voltage 0.6V and power consumption is 0.882mW. Gain is 15.1dB and NF is 3.75dB. The die area is 0.99 x 0.69. For proposed VCO with low voltage and low power consumption, the cross-coupled NMOS pair with the extra symmetric center tapped inductor between the source ends of the cross-coupled transistors is adopted to reduce the phase noise. Furthermore, the capacitive-divided feedback is connected between drain and source terminals of the devices, resulting in increased output voltage swings and improved phase noise. The proposed VCO consumes roughly 2.9mW. The phase noise is -116.5dBc/Hz. The die area is 1.3 x 0.67 .
