This thesis uses TSMC 0.18μm 1P6M CMOS process’s RF model to design two Ultra-Wideband LNAs, it is applied on the systems of the IEEE 802.15.3a Wireless Personal Area Network (WPAN). One LNA is operating at 3G~5GHz, using folded cascade with Miller frequency compensation and introducing a zero to expand the bandwidth. Besides, the structure of PCSNIM[17] is introduced to obtain optimal design among noise, matching and power dissipation. And then, the following second stage can increase the gain higher than 15dB. By the Miller’s equivalent impedance of the shunt-shunt feedback, the input impedance matching can be achieved. The other LNA is designed operating at 3G~10GHz, using the wideband differential pair to achieve flat broadband gain and using the SNIM[17] structure with inductance and capacitance compensation to expand the bandwidth. The Advanced Design System (ADS) is used to simulate the design circuits and the chips are fabricated and measured by the aids of the CIC. Chang-si Wu 吳常熙 2008 學位論文 ; thesis 99 zh-TW |
