一种用于多标准接收机的宽带低噪声放大器
A wideband low noise amplifier for multi-standard receivers
摘要
Abstract
A 300 kHz -1.6 GHz wideband CMOS low noise amplifier ( LNA) for software-defined radio receivers was de-signed. It is fit for the applications in digital radio, digital TV and global position systems. The channel thermal noise and the flicker noise of the input metal oxide semiconductor field effect transistor (MOSFET) is canceled by exploiting a noise canceling technique. A lower noise figure and an excellent wide-band input matching can be achieved at the same time. It was designed in SMIC s 0.18 μm RF CMOS process. The measured results show that in the band of 300 kHz -1.6 GHz, the maximum gain SP/G network; successive over-relaxation (SOR);open defect; algorithm; incomplete Cholesky decomposition conjugate gradient (ICCG)_(21) is 16.7 dB, the input reflection factor S_(11) is lower than - 7.4 dB, the minimum noise figure (NF) is 2.3 dB, and the input-referred 1-dB gain compression point is 11.6 dBm. Its consuming power is 14.4 mW. The chip area is 0.49 mm .关键词
