摘要
Ultra wideband (UWB) low-noise amplifiers (LNA) are one of the key features in modern radiofrequency and microwave receivers. This paper presents an enhanced 3-7 GHz common-source LNA in 130nm CMOS technology. Coupled to an inverse Tchebycheff band-pass filter, the proposed system led to a high gain while reducing the noise distribution and improving the amplifier linearity. Indeed, with a power consumption of 5mW, a return loss less than -13dB, a maximum gain of 15dB with 0.01dB ripple, a minimum noise figure less than 1.6dB, and a third order intercept point greater than 6.7dB, the proposed UWB low-noise amplifier demonstrated its excellent performance over similar published designs.
