Journal ArticleDOI
A 1 V Micropower FGMOS Class AB Log-Domain Filter
TL;DR: In this paper, a first-order CMOS log-domain filter is presented, which allows operation with a single 1 V supply while maintaining at the same time a large input range.
Journal ArticleDOI
±1.5V 3mW CMOS V--I converter with 75 dB SFDR for 6V/sub pp/ input swings
TL;DR: In this article, a novel CMOS voltage-to-current converter topology is proposed, where the use of nested local feedback loops and the absence of current replication in the signal path provide low sensitivity to transistor mismatch and high linearity.
Journal ArticleDOI
Low-power baseband filter for zero-intermediate frequency digital video broadcasting terrestrial/handheld receivers
C. Lujan-Martinez,Ramon G. Carvajal,Antonio Torralba,Antonio J. Lopez-Martin,Jaime Ramirez-Angulo,U. Alvarado +5 more
TL;DR: A continuous-time filter for DVB-T/H receivers is presented, selected by selecting a Gm-C filter topology implemented with a novel programmable transconductor based on MOS transistors in the triode region.
Journal ArticleDOI
Class AB differential difference amplifier for enhanced common-mode feedback
TL;DR: In this paper, a class AB differential difference amplifier for continuous-time commonmode feedback (CMFB) is presented, which employs local CMFB to improve gainbandwidth product and dynamic performance of the CMFB loop, without increasing static power consumption or supply voltage requirements.
Journal ArticleDOI
Low-Voltage CMOS Nonlinear Transconductors and Their Application to Companding Current-Mode Filters
TL;DR: In this paper, two nonlinear transconductors that can be employed for building CMOS current-mode filters are presented and their performances compared to previously proposed topologies aimed at the same goal.
