Abstract:

The article discusses the design method of operational trans-conductance amplifier-C(OTA-C) filter based on the prototype of LC filter. It gives the OTA circuit used in the filter. And it makes a detailed analysis on characteristics of OTA. A third order OTA-C filter is presented. Its cut-off frequencies can be tuned by the bias DC current of OTA. The filter is easy to integrate. The proposed OTA has been simulated in CMOS technology. Simulation results show that the repose of the OTA-C filter and passive LC filter is almost the same. And it can be used in middle to high frequency circuit.
