Projeto e análise de moduladores Sigma-delta em tempo contínuo em tecnologias CMOS
(BrasilUFSMCentro de Tecnologia, 2014-12-05)
This work presents the design of a continuous time sigma-delta modulator with a 0.2
MHz signal bandwidth and 78 dB signal-to-noise ratio (SNR), which are the specifications for
the GSM standard. Three single-loop, ...
A constant temperature operation thermoresistive sigma–delta solar radiometer
(2006)
In this paper we propose a feedback system, with thermoresistive sensor, based on sigma–delta modulation. This system uses an one-bit sigma–delta modulator in which considerable part of conversion functions is performed ...
