Current differencing transconductance amplifier (CDTA) is a very useful alternative building block of current mode operational amplifiers. The analog filter types designed with CDTAs can be implemented by using only capacitors. A new reconfigurable filter employing CDTAs structure for analog signal processing is proposed in this paper. The filter structure consists of CDTAs and only two capacitors as passive element. The proposed filter structure is a part of different positioning protocols to implement on the same chip. The filter is designed with AMS 0.18 mu m technology. The filter performance is tested and verified by simulations with Cadence environment.
