Abstract:	我們提出了一個多段的近似方法來設計一個CMOS電流模式的雙曲正切Sigmoid函數具有精度高和寬的輸入動態範圍的功能。動態範圍是與段數和精度有關，從數學結果，我們可以觀察該方法優於傳統方法。我們實現了多段逼近電路實現雙曲正切Sigmoid函數，所提出的電路模擬結果顯示，具有寬的輸入動態範圍從-256 uA到240 uA，相對誤差小於3％和具有138 MHz的高頻寬。 We propose a multi-segment approximation method to design a CMOS current-mode hyperbolic tangent sigmoid function with high accuracy and wide input dynamic range. The dynamic range is dependent on the number of segments and the accuracy is related to the
