Chanapromma and T. Worachak and P. Silapan}, country = {}, institution = {}, abstract = {This paper presents positive and negative full-wave rectifier. The proposed structure is based on OTA using commercially available ICs (LT1228). The features of the proposed circuit are that: it can rectify and amplify voltage signal with controllable output magnitude via input bias current: the output voltage is free from temperature variation. The circuit description merely consists of 1 single ended and 3 fully differential OTAs. The performance of the proposed circuit are investigated though PSpice. They show that the proposed circuit can function as positive/negative full-wave rectifier, where the voltage input wide-dynamic range from -5V to 5V. Furthermore, the output voltage is slightly dependent on the temperature variations.}, journal = {International Journal of Electronics and Communication Engineering}, volume = {5}, number = {10}, year = {2011}, pages = {1083 - 1086}, ee = {https://publications.waset.org/pdf/934}, url = {https://publications.waset.org/vol/58}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 58, 2011}, }
