I. Introduction
Now a days continuous time voltage integrator is one of the basic building blocks of analog signal processing systems like active filters, data converters(ADC) and signal generator etc [1]. Majorly there are three types of integrators like active R-C integrators, OTA-C integrator and MOSFET-C integrators as shown in Fig 1. ActiveR-Cintegrators(OpAmpRC) are not suitable for low power application because of high power dissipation of op Amp [4].The speed of active RC integrator are limited by closed loop feedback. MOSFET-C type integrator usually operates in strong inversion region which might not be a feasible solution for ultra low voltage supplies [2]. The speed of OTA-C type is very high compared to other two types [3]. But because of closed feed back gain and bandwidth are low which can be increased by using Gm-C architecture. The only demerit of Gm C integrator type is poor linearity. In order to overcome this non linear behavior a new OTA is used which balance the non linear behavior of Gm C cell.
