Multi Input Single Output using Operational Transresistance Amplifier as First Order Filter

The following research paper gives a different type of voltage mode multifunction filter which is of first order, which consist of only one OTRA block that is operational transresistance amplifier and few of the passive components. This structure can be used for employing different types of filter functions of 1
^st
order. The proposed device is simulated with the parameters of 0.5μm CMOS which is defined by MOSIS (AGILENT). The results are verified using simulation software PSPICE.
