Voltage mode universal filter design using CCDDCCTA

This article presents a voltage mode filter. This circuit has the following important features: It is designed using CCDDCCTA. All response like LP, HP, BP, AP, & notch are obtained without alteration of the configuration. Response of all filters is electronically tunable and Low sensitivity. Operation of proposed circuit is tested using 25μm CMOS process through PSPICE simulation. Simulated outputs match with the theoretical results.
