Modeling and design of a Folded Cascode bulk driven OTA
7th International Conference on Design & Technology of Integrated Systems in Nanoscale Era, 2012Analog circuit design is often based on a large number of simulations which strongly depends on the mastery of CAD tools and competence of the designer. In this context, the automated design of analog architectures becomes a necessity of design to solve the problem of simulation time. More importantly, accelerating the design cycle of the analog block,

Low-voltage bulk-driven rectifier for biomedical applications
Microelectronics Journal, 2013This paper introduces the novel design of a low-voltage low-power voltage rectifier based on bulk-driven (BD) winner-take-all (WTA) circuit. The proposed circuit is able to work as a half- or full-wave rectifier and it is specifically designed for battery-powered implantable and wearable medical devices.

An efficient approach to enhance bulk-driven amplifiers
Analog Integrated Circuits and Signal Processing, 2017In this paper, a single-stage class AB bulk-driven amplifier operating in weak inversion region is proposed. The presented amplifier benefits from an improved high input swing structure using quasi-floating-gate technique. The composite transistors and recycling configuration used at the input stage enable the input differential pair to operate under ...

A Compact 0.3-V Class AB Bulk-Driven OTA
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2020In this article, a new solution for an ultralow-voltage (ULV) ultralow-power (ULP) operational transconductance amplifier (OTA) is presented. Thanks to the combination of a low-voltage bulk-driven nontailed differential stage with the multipath Miller zero compensation technique, a simple class AB power-efficient ULV structure has been obtained, which ...

0.8 V bulk-driven operational amplifier
Analog Integrated Circuits and Signal Processing, 2009A low-voltage bulk-driven CMOS operational amplifier is proposed in this paper. The inherent small transconductance of the bulk-driven devices is enlarged using a positive feedback, improving also the noise performance. The amplifier is designed using standard 0.18 μm n-well CMOS process. Although the amplifier is optimized for 0.8 V supply voltage, it

Designing bulk-driven MOSFETs in scaled technologies
2009 International Semiconductor Device Research Symposium, 2009With the advent of system-on-a-chip integration, analog components are being forced to co-exist with their digital counterparts in scaled processes where the supply voltage, V DD , is expected to fall to 0.7 V by 2012 [1]. As a result of this integration, traditional analog topologies suffer from voltage headroom constraints since the threshold voltage,

This paper focuses on the usage of non-conventional techniques viz. Bulk-driven (BD) and Bulk-driven-quasi-floating-gate (BDQFG) to design low-voltage (LV) and low-power (LP) pre-amplifier for electroencephalogram (EEG). Gate–Driven (GD) Three-Current-Mirror Operational Trans-conductance Amplifier (OTA) is compared with BD-OTA and BDQFG-OTA.

A bulk-driven ISFET-based chemical mixer
2010 Biomedical Circuits and Systems Conference (BioCAS), 2010In this work the concept of the chemical mixer for comparing the pH of two aqueous solutions is introduced. Ionic concentrations are sensed via a pair of ISFETs, which are then translated into signals with frequencies that correspond to the pH values of the solutions.
