Micropower active-RC channel filter for a zero-IF Bluetooth receiver
Juan Antonio Gómez Galán,T. Sánchez-Rodríguez,C. Lujan-Martinez,M. Pedro,Ramon G. Carvajal,Antonio J. Lopez-Martin +5 more
TL;DR: In this article, a fourth-order low-pass channel filter for a zero-IF Bluetooth receiver is presented, which employs two cascaded multiple feedback biquads and active resistors made by quasi-floating gate MOS transistors in triode region for highly linear continuous tuning.
Radio-Planning, Energy Efficiency, and System Integration
Francisco Falcone,Antonio J. Lopez-Martin,Carlos Fernández-Valdivielso,Luis Serrano,S. Led,Miguel Martínez de Espronceda +5 more
TL;DR: In this article, the impact of radio-planning strategies, transceiver elec- tronic design, and overall wireless system planning is discussed, by following a complete approach, from physical layer limitations derived from radiopropagation losses to transceiver requirements and the functional elements of the overall wireless systems.
Journal ArticleDOI
A Review of Techniques to Enhance an Amplifier’s Performance Using Resistive Local Common Mode Feedback
Jaime Ramirez-Angulo,Antonio J. Lopez-Martin,Ramon G. Carvajal,Antonio Torralba,J. Huerta-Chua +4 more
TL;DR: A review of some of the most common applications of the resistive local common mode feedback technique to enhance amplifier's performance is presented in this paper , where it is shown that this simple technique offers essential improvement in open loop gain, gain-bandwidth product, slew rate, common mode rejection ratio, power supply rejection ratio etc.
Journal ArticleDOI
Low-Voltage Rail-to-Rail Tunable FGMOS Transconductor
TL;DR: In this article, the combined use of a FGMOS differential pair and a floating DC level shifter allows the use of low supply volatages while maintaining at the same time a rail-to-rail input range, low distortion and high linearity.
Proceedings ArticleDOI
An Input Stage for the Implementation of Low-Voltage Rail to Rail Offset Compensated CMOS Comparators
Jaime Ramirez-Angulo,L.M. Kalyani-Garimella,Annajirao Garimella,S.R.S. Garimella,Antonio J. Lopez-Martin,Ramon G. Carvajal +5 more
TL;DR: Experimental results obtained from a MOSIS 0.5 mum CMOS technology test chip are shown that validate rail-to-rail operation with a 1.5 V supply voltage.
