2 Single-stage amplifiers
Nowadays, the need of broadband transceiver is rapidly increasing, so we review the design method of RF front-end for UWB receiver and design RF front-end that support UWB (UWB PHY layer of IEEE 802.15.3a). This paper shows the design of an Ultra Wide-Band (UWB) Low Noise Amplifier (LNA) for the frequency range 3.1 GHz to 10.6 GHz to base on 0.18μm RF CMOS technology. The amplifier adopts the shunt-feedback and common-source for the two-stage architecture, including broadband matching techniques to achieve the input and output impedance matching. The shunt-feedback improves the stability and noise figure (NF), and common-source does output matching. The input matching is used to the inter-stage.
