This brief proposes a 0.25 V rail-to-rail three stage OTA. The proposed OTA improves a DC gain by inserting an NMOS gate-driven amplifier into the conventional bulk-driven OTA. In …
This article presents a low-voltage high-transconductance input differential pair for bulk- driven amplifiers. The proposed structure employs two bulk-driven flipped voltage follower …
A bulk-driven operational transconductance amplifier (OTA) suitable for ultralow-power and ultralow-voltage applications is described. The amplifier exploits local positive feedback in …
A novel, inverter-based, fully differential, body-driven, rail-to-rail, input stage topology is proposed in this paper. The input stage exploits a replica bias control loop to set the …
A novel architecture and design approach which make it possible to boost the bandwidth and slew-rate performance of operational transconductance amplifiers (OTAs) are proposed …
A tail-less, fully differential trans-conductance amplifier is presented in this paper. The proposed structure arranges the current push-pulls as the core amplifier blocks in an …
This paper presents a calibration-less inverter-based operational transconductance amplifier (OTA) built with intrinsically matched CMOS inverters, therefore, dispensing any …
