Synthesis of Linear Transfer Functions Based on OTA
Tan Zi · Development & Innovation of Machinery & Electrical Products · 2006
The paper presents a general methodology for synthesis of linear analog transfer functions based on the network of operational transconductance amplifiers(OTAs). The transfer fuctions are decomposed into two lowpass filters which are synthesized with the OTA blocks in serial. The paper describes the synthesis process, the circuit structure and realization. At last the fourth order Butterworth bandpass filter are simulated in pspice to show that the method is correct and feasible.
