To achieve low power consumption and wide operating bandwidth, the proposed Pre-amplifier employing low power dc feedback current reuse distributed amplifier which the dc current flows through the PMOS to NMOS transistors to reuse the same bias current.

The maximum output power of 2dBm has been measured. In this thesis, design optimization for the low power current reuse distributed amplifier in wide bandwidth applications is also presented. The novel topology of current reuse distributed amplifier is applied to the RF front-end design for the UWB direct conversion transmitter and uses the feedback resistance to fix the output dc voltage in order to maintain excellent performance. In the RF front-end, a wideband passive mixer is designed for the purpose of low power, and high bandwidth before the Pre-amplifier. The measurement results exhibit that the UWB direct conversion transmitter of package version achieves conversion gain of -12dB from 3-8.3GHz with ±2 dB variation, and obtain the maximum output power of 0dBm at LO frequency 3.4GHz. The UWB transmitter front-end referenced to the band group #1, 2 and 3 of the Multi-Band OFDM with operation frequency range 3-8.3 GHz demonstrates low power, high gain, and wide bandwidth. It is also verified by a RF/Baseband co-simulation. Kuei-Ann Wen Wen-Shen Wuen 溫瓌岸 溫文燊 2005 學位論文 ; thesis 75 zh-TW |
