摘要：Ultra wideband systems find applications in indoor and high speed applications. Being baseband transmission, it exhibits properties like low power and low cost design. Especially, IR-UWB systems demonstrate such characteristics. The performance of IRUWB system is mainly dependent on LNA design. In this paper we have designed three LNA’s, a wide band and two low band. A SIMULINK based transmitter and receiver model is designed based on BPSK to evaluate the performance. The wide band LNA is phase linear and one low band LNA is noise cancellation type. Both LNA designs are tested on Agilent’s ADS software for 25 micron technology. The wide band LNA gives flat gain over 12 dB. The low band LNA gives good noise figure 4.06 dB. The simulation is carried out to check the BER of BPSK transmitter and receiver. The simulation result shows the low band LNA with noise cancellation performs better than ‘without’ noise cancellation. The system with wideband LNA having phase linear characteristics gives good BER performance as compared to low band LNA.
