متن کاملThe Design of a 17.35 GHz LNA and Mixer
The performance of radio-frequency integrated circuit (RFIC) blocks such as low noise amplifiers (LNA) or mixers is enhanced by achieving a simultaneous noise and power match at the input. This paper presents a design strategy for achieving this match for circuits built from bipolar transistors with inductive degeneration. The strategy is applied to the design of a 17.35 GHz LNA and a 17.35 GHz...
متن کاملCMOS LNA and Mixer Components for 2GHz applications in 0.18-μm CMOS
This paper describes a low noise variable gain amplifier (LNA) and a mixer for a WCDMA frontend receiver based on a direct architecture in 0.18-μm CMOS. The LNA provides a 50Ω input impedance and utilizes a tuned load to provide high selectivity. The LNA achieves a maximum small signal gain of 16.8 dB and a minimum gain of 4.6 dB with good input return loss. In the high gain and the low gain mo...
متن کاملAn interference-robust wideband LNA with balanced outputs
This thesis presents a noise-canceling LNA based on a complementary common-gate commonsource combination. It provides active balun functionality with a single-ended input that is power matched to the antenna and a differential current output driving a passive mixer. By allowing class AB operation for both outputs, the LNA achieves a high compression point and its outputs remain balanced under i...
متن کاملA 1.5-V, 2.4-GHz CMOS LNA and Mixer Receiver Front-End
There are two main approaches to realize a receiver front-end. However, they have drawbacks when fully-integrated on a single chip. One direction to realize this front-end is to use a transformer that can convert the single RF output of the LNA to the differential input of mixer [4]. Another way to do this is to use a narrow-band two stage tuned LNA [5] that can provide a differential output. H...
