Abstract :
A flexible synthesis procedure for generating current-mode active filters using current differencing transconductance amplifiers is given. The proposed method is based on drawing the signal-flow graph from the given transfer function and obtaining the circuit realization from the graph. By using this method, a new nth-order low-pass filter is proposed. The simulation results for the sixth order Butterworth filter are also included.
