Issue Date: | 2010 | Publisher: | 0192-6225 | Journal: | Microwave Journal | Abstract: | A novel configuration to achieve flat gain in wideband low noise amplifiers (LNA) is presented. It consists of a conventional shunt-peaking resistor, decoupled from the cascode stage through a capacitor. A trade-off between the voltage headroom and bandwidth is obtained, improving the traditional shunt-peaking load. As an example, two LNAs for ultra-wideband (UWB), operating for mode I (3.1 to 4.8 GHz), are designed in CMOS 0.35 μm technology. The measured power gain is fairly flat, approximately 10 dB, for frequencies ranging from 3.1 to 5 GHz. | URI: | http://hdl.handle.net/10553/45462 | ISSN: | 0192-6225 | Source: | Microwave Journal[ISSN 0192-6225],v. 53, p. 74-82 |
