Iran has variations in the incidence of cancer in its different provinces. Moreover, it is one of the countries with a high incidence of gastrointestinal cancers in the world. The aim of this study was to investigate the relation between the incidence of esophageal, stomach, and colon cancers with ultraviolet radiation. This is an ecological study. The age-standardized incidence of cancer from 2004...
High performance MEMS gyroscopes can be implemented by embedding in a closed loop controller. For these gyroscopes, the electrostatic controlled force on the proof mass is inherently nonlinear. This study reports a MEMS gyroscope with control capability in which comb drive electrodes are employed as the controlling mechanism to linearize the electrostatic controlled force. To avoid interaction of...
Dual mode high performance reconfigurable continuous time delta sigma modulator with concentration on reducing the active blocks and power saving is presented in this article. The modulator makes use of a low distortion suppression topology which is suitable for wide band applications and a Noise Shaping Enhancement (NSE) technique for increasing the performance of the modulator. A None Return to...
This paper presents a design and simulation of a reconfigurable delta sigma modulator (DSM) that can handle GSM / WCDMA/ WLAN standards. The modulator makes use of a low distortion suppression topology which is suitable for wide band application. In GSM mode a 2nd order DSM is used to achieve a peak SNR of 90 dB with over sampling ratio of 160 for bandwidth of 0.2 MHz. for WCDMA mode a 2nd order DSM...
