The Design of High-frequency OTA-C filter For Wireless Sensors Network Applications
The paper is presented the design of high-frequency OTA-C band-pass filter with on-chip automatic tuning.In this design,the linear operational transconductance amplifier (OTA) is proposed based on fully complementary differential pairs with source degneration,and achieves both low-distortion figures and high-frequency operation.The matching design between the master filter and the slave filter is also given,and the non-ideality effect of the OTA-C filters with on-chip automatic tuning is discussed.The whole circuit is designed using TSMC 0.18μm 1.8V CMOS process and post-simulation results show the center frequency of filter is 105MHz with relative error of 0.4%,when the process corner varies between SS,TT,FF,and the temperature from -20 to 120℃.
