In this work, a new solution for an ultra-low-voltage, (ULV) ultra-low-power (ULP) operational transconductance amplifier (OTA) is presented. Thanks to the combination of a low-voltage bulk-driven non-tailed differential stage with the multipath Miller zero compensation technique, a simple class AB power-efficient ULV structure has been obtained, which can operate from supply voltages less than the threshold voltages of the employed MOS transistors, while offering rail-to-rail input common-mode range at the same time. The proposed OTA was fabricated using the 180 nm CMOS process from TSMC and can operate from VDD ranging from 0.3 to 0.5 V. The 0.3-V version dissipates only 12.6 nW of power, while showing a 64.7 dB voltage gain at 1 Hz, 2.96 kHz gain-bandwidth product and a 4.15 V/ms average slew-rate at 30 pF load capacitance. The measured results agree well with simulations.
