In this paper, we present a novel operational transconductance amplifier (OTA) topology based on a dual-path body-driven input stage that exploits a body-driven current mirror-active load and targets ultra-low-power (ULP) and ultra-low-voltage (ULV) applications, such as IoT or biomedical devices. The proposed OTA exhibits only one high-impedance node, and can therefore be compensated at the output stage, thus not requiring Miller compensation. The input stage ensures rail-to-rail input common-mode range, whereas the gate-driven output stage ensures both a high open-loop gain and an enhanced slew rate. The proposed amplifier was designed in an STMicroelectronics 130 nm CMOS process with a nominal supply voltage of only 0.3 V, and it achieved very good values for both the small-signal and large-signal Figures of Merit. Extensive PVT (process, supply voltage, and temperature) and mismatch simulations are reported to prove the robustness of the proposed amplifier.

Simulation Results

This paper presents different low voltage adjustable CMOS Schmitt trigger using DCG-FGT transistor. Simple circuits are introduced to provide flexibility to program the hysteresic threshold in this paper. The hysteresis can be controlled accurately at a large voltage range. The proposed Schmitt trigger have been designed using 90nm 1.2V CMOS technology and simulated using Eldo with PSP device models. The simulation results show rail-to-rail operation and adjustable switching voltages <em>V<sub>TH- </sub></em>(low switching voltage) and <em>V<sub>TH+ </sub></em>(high switching voltage).
