Abstract
In this work, a two-stage operational transcoductance amplifier (OTA) has been designed and is used to design various active filters as an application. The main contribution of this work is in the direction of achieving high gain, high bandwidth, high PSRR, and low noise for the proposed OTA. Over the years, different methodologies have been proposed by researchers to enhance the performance of OTA. In this work, the proposed results have been analytically verified with theory and compared with the related work. In this work, 90 nm technology is used for simulations which are carried out using Tanner EDA 16.0 tool and these results are compared with related work performed using 180 nm technology. With the help of this work, a two-stage OTA can be designed having high gain, high bandwidth, high PSRR, etc., and various active filters can also be designed with the help of this OTA, for filtering purposes.
