- This paper presents designs and measurements of distributed amplifiers (DAs) processed on a 130-nm silicon-on-insulator CMOS technology on either standard-resistivity (10 Omega . cm) or high-resistivity (>1 k Omega . cm)...
- A high conversion-gain Q-band InP DHBT subharmonic mixer using LO frequency doubler
[作者:Johansen, TK; Vidkjaer, J; Krozer, V; Konczykowska, A; Riet, M; Jorge, F; Djurhuus, T,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:613-619 , 文章类型: Article,,卷期:2008年56-3]
- The paper presents analysis and design of a Q-band subharmonic mixer (SHM) with high conversion gain. The SHM consists of a local oscillator (LO) frequency doubler, RF pre-amplifier, and single-ended mixer. The SHM has b...
- A new RF CMOS Gilbert mixer with improved noise figure and linearity
[作者:Yoon, J; Kim, H; Park, C; Yang, J; Song, H; Lee, S; Kim, B,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:626-631 , 文章类型: Article,,卷期:2008年56-3]
- The noise figure of an RF CMOS mixer is strongly affected by flicker noise. The noise figure can be improved using pMOS switch circuits, which insert current at the on/off crossing instants of the local oscillator switch...
