This paper presents an innovative topology for an operational transconductance amplifier (OTA) based on a CMOS inverter topology. This OTA is proper for biomedical and healthcare circuits and systems, due to a low level of noise and power consumption, together with elevated gain. This is a fully-differential implementation, with a double CMOS branch biased by two pairs of voltage-combiners, in both NMOS and PMOS configurations, highly improving the gain and the gain-bandwidth product, improving the OTA energy-efficiency. An elevated figure-of-merit is achieved, i.e., a 1628 MHz×pF/mA, and a gain of 53 dB, under a voltage supply source of 2 V. The results are compared with state-of-the-art OTAs in this field of study and the potential is fully fulfilled with a state-of-the-art layout-aware optimization tool, AIDA, particularly important to overcome the device stacking problematic in lower supplies. |
