MOSFET model assessment for submicron and nanometer bulk-driven applications
2009 Canadian Conference on Electrical and Computer Engineering, 2009Bulk-driven MOSFET technique meets the low-voltage and low-power requirements demanded in the modern analog circuit design. Due to submicron/nanometer technologies and critical short-channel effects, choosing a suitable MOSFET model for circuit design becomes increasingly important.

Low‐voltage bulk‐driven input stage with improved transconductance
International Journal of Circuit Theory and Applications, 2011AbstractA low‐voltage input stage constructed from bulk‐driven PMOS transistors is proposed in this paper. It is based on a partial positive feedback and offers significant improvement of both input transconductance and noise performance compared with those achieved by the corresponding already published bulk‐driven structures. The proposed input stage

Built-in current sensor designs based on the bulk-driven technique
Proceedings Sixth Asian Test Symposium (ATS'97), 2002Recently the bulk-driven current mirror technique has been employed in built-in current sensors for low voltage environment. This paper proposes 4 arrangements of built-in current sensors based on this technique. They are mainly different in biasing schemes end respectively take the advantages of simplicity, accuracy, flexibility and low power ...

Comparison of gate-driven and bulk-driven current mirror topologies
2016 IEEE 19th International Symposium on Design and Diagnostics of Electronic Circuits & Systems (DDECS), 2016In this paper, different topologies of gate-driven and bulk-driven current mirrors designed in 90 nm CMOS technology are presented. Since the conventional MOS transistors can work as a bulk-driven device, there is no need for any modification of the existing MOSFET structure or technology process.

Low-Voltage Bulk-Driven Operational Amplifier With Improved Transconductance
IEEE Transactions on Circuits and Systems I: Regular Papers, 2013This paper presents two low-voltage bulk-driven amplifier input stages with enhanced transconductance. The idea is to introduce auxiliary differential pairs into a conventional bulk-driven stage to boost its transconductance. A low-voltage cascode biasing circuitry based on EKV models is also employed to ensure proper operation of the proposed input ...

0.7-V bulk-driven three-stage class-AB OTA
2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS), 2015A high-performance architecture for bulk-driven operational transconductance amplifiers (OTAs) is presented. The solution exploits a three-gain-stage topology and, as a distinctive behavior, provides an inherent class-AB performance with simple and robust standby current control.
