Linearity Enhancement Technique for GHz-Band LNA
This paper presents linearity enhancement technique for GHzband low noise amplifier (LNA). To verify this technique, we designed LNA using 0.18-μm BiCMOS process. Linearity is very important parameter for LNA. The MOS-BJT derivative superposition (MBDS) technique is exploited by a parallel LC tank in the emitter of bipolar transistor to reduce the secondorder non-linear coefficient (gm2) relate...
متن کاملA Linearity-Improved Ultra-Wideband Balun-LNA for Cognitive Radio
An ultra-wideband low noise amplifier for cognitive radio applications covering 50 MHz to 10 GHz is designed in a 65-nm CMOS technology. A three-stage dc-coupled common source amplifier with RC degeneration at the last stage optimizes the gain, linearity and output gain-phase balancing. Throughout the covered band, the simulated voltage gain is >23.3 dB whereas the noise figure is <3.4 dB. The ...
متن کاملNon-Linearity in Wide Dynamic Range CMOS Image Sensors Utilizing a Partial Charge Transfer Technique
The partial charge transfer technique can expand the dynamic range of a CMOS image sensor by synthesizing two types of signal, namely the long and short accumulation time signals. However the short accumulation time signal obtained from partial transfer operation suffers of non-linearity with respect to the incident light. In this paper, an analysis of the non-linearity in partial charge transf...
متن کاملLinearity Improvement Technique for the Common-Source Transconductance Stage
A linearity improvement technique for a common-source transconductance stage is proposed. The proposed technique requires an additional MIM capacitor located in parallel with the intrinsic gate-source capacitor of a transistor. The origin of the linearity improvement is explained and the proposed technique is applied to a down-conversion mixer. From the simulation, the down-conversion mixer tha...
متن کاملA High Linearity VHF Programmable Gain LNA
A VHF (30MHz-300MHz) band digitally programmable low noise amplifier (LNA) has been implemented with a 0.25um standard CMOS process for VHF CMMB mobile TV tuners. Utilizing a T-match input network, input matching of more than a decade bandwidth is achieved across all gain settings. Adopting the multiple gated technique, gain flatness enhancement and capacitor reuse etc., the proposed LNA demons...
