Abstract

This paper presents designing of first order low pass filter using Operational Transconductance Amplifier (OTA). This paper illustrates an application of OTA as an active low pass filter. The primary building block of an OTA is the current mirror. Different current mirrors are used to design the LPF & the corresponding frequency and phase responses are comparatively studied in this paper. With comparatively CMOS OTA & NMOS OTA are to study but also illustrated in this article.
