In this paper, a low power low transconductance operational transconductance amplifier (OTA) is designed for biomedical application such as the EEG and ECG. To achieve a very low transconductance with low power the OTA should operate in sub threshold region. For better linearity of the OTA, the multi-tanh doublet linearization technique is used. In this design 90nm CMOS technology is used with ±0.35V supply voltage. The linear range of the OTA is 200mV and the power dissipation is below 6nW. The transconductance value of the OTA is 50nS for biomedical EEG Application and 62.68mS for biomedical ECG Application, Which can be tuned by varying in control voltage VC. The 3-db cutoff frequency required for ECG and EEG is 250Hz and 200Hz respectively.
