In the recent years there is rapid growth in the CMOS technology, which made analog integrated circuits to dominate today’s existing market which provides low cost, and excellent performance of systems. Now-a-days wide band analog signal processing helps to find variety of applications in telecommunications and for the medical electronics. Since we prefer continuous time filtering for the low voltage, low power applications. An analog LPF forms the main building block in all of the systems. The operational transconductance based OTA is selected for the realization of analog filter due to their structural simplicity and monolithic integrability. In this paper a telescopic cascade single stage OTA was designed.
