Yanpeng Wang, Gao Guanwang, Sha Zhanyou, Shian Li · 2007
Using Digitally Controlled Potentiometers all kinds of programmable Tee networks can be composed. The paper introduces the base structure of the Tee networks. Then expatiates the design of the programmable Tee networks and the application examples in the analog system, which includes controlling the limiting frequency of the amplifier, controlling the coefficient of IGSF active filter and the design of current / voltage (I/U) converter.
