Abstract
The aim of this paper to probe into the low power voltage amplifier which can achieve the high gain and fine flatness. The high gain Low Noise Amplifier (LNA) was designed for an Ultra Wide-Band (UWB) application. This CMOS LNA with three cascade circuits can enhance the gain and bandwidth, middle inductor can suppress the miller effect, and used the RC feedback network to maintain the flatness. Input matching stage adopts an improved Chebyshev filter to achieve the input return loss and the source follower applied to the output matching. The UWB LNA exhibits the maximum gain S21 is 17.74 dB. The power consumption is 13.08 mW at VDD=1 V.
