SIGNAL FLOW GRAPH OTA-C HIGH-PASS FILTERS
信号流图OTA-C高通滤波器

A design technique for high-pass filters using OTA differentiator is presenred. By means of the leapfrog synthesis of the active filters, the OTA-C realization of the highorder high-pass filters is built up. The filter is compatible with MOS process. It has low sensitivity performance and high cut-off frequency, and can be tuned conveniently by the external voltages. Experimental results and P-SPICE simulation are given to prove its feasibility
