Abstract :In this study, a new CMOS differential OTRA topology is proposed. This topology can operate with a very low voltage power supply as \pm 0.6V. In this design, CMOS 0.13 m m STMicroelectronics technology transistor models are used for the simulations. The designed CMOS OTRA has a transresistance gain insert ignore into journalissuearticles values(Rm); of 7478 V/I with a 28.1 MHz bandwidth insert ignore into journalissuearticles values(-3 dB); and a transresistance unity-gain bandwidth of 2 GHz. To demonstrate the performance of the OTRA, designed low pass, high pass and band pass filters employing a single CMOS differential OTRA and passive elements are tested with SPICE simulation program to verify the theoretical results.
