Abstract :
A study of the implementation of integrated MOSFET-C continuous-time filters in SOI technology is presented. A detailed comparison of both the bulk and SOI linearity performances of two- or four-transistor balanced structures is given and provides the experimental demonstration of the superiority of the four-MOSFET over two-MOSFET structures as well as of SOI over bulk. Furthermore, to keep a good filter linearity, the use of a simple OTA-like amplifier is also discussed. Design and measurement of a complete MOSFET-C SOI CMOS audio-equalizer is finally reported.
