This paper presents the design of folded cascode operational transconductance amplifier (OTA). This
design has been implemented in 0.18um CMOS Technology using Cadence. Spectre simulation shows
that the OTA has flat gain of 47dB from 1Hz to 100 KHz frequency, indicating stability of OTA, noise
ranges as 22.49769nV/ at 10Hz to 66.89128fV/ at 1MHz and average power as 0.770mW. In
this paper, we will be studying the design concepts, analysis of operational transconductance amplifier
which is used for recording the bio signals. This paper plays a key role in real time applications for
equipment designing of ECG, EEG, EMG, ENG devices. It is also used in recording and also for
treatment of Paralysis, Epilepsy, Neuro diseases etc.,
