摘要：

In this paper, a Tow-Thomas biquadratic filter designed in square root domain is proposed. The presented filter is constructed with a lossy integrator, a lossless integrator, and a summer block. To the best knowledge of the authors, the filter is the first square root domain Tow-Thomas filter in the literature. The state space synthesis method is used to design the biquadratic filter. The filter operated at 2.5 V supply voltage is simulated by using SPICE simulation program with 0: 25 mu m TSMC CMOS model parameters. Simulation results are in good agreement with theoretical results that the cut-off frequency and quality factor of the filter are tunable electronically.
