Active network synthesis is important for circuit designer to find new circuits with desired performance. In this paper, a method of Tow-Thomas (TT) Bi-quad band-pass filter circuit generation methods is proposed using nullor representation of the operational amplifier (OPA), and a method for synthesizing active band-stop filters is presented, both of which start from voltage transfer function ...

This paper presents, a new and simple CMOS realization of VDTA is presented. And the proposed block use for the design of an electronically tunable Tow-Thomas biquad filter. The presented filter is constructed using two VDTAs, two capacitors all are grounded. This circuit simultaneously realizes Low Pass and Band Pass filter responses, without changing the circuit topology. Tow-Thomas biquad fi...

A 40 year old man sustained a flaccid paralysis of his right upper extremity in a water skiing accident on August 22nd, 1976. At the time of the injury the patient was being towed on water skis, when another boat cut across his tow rope. The force of the boat hitting his tow rope, combined with the wakes of both boats, caused the patient to be thrown forcefully into the air, with his right arm ...
