Transconductance enhancement in bulk-driven input stages

2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008
This paper presents two different circuit techniques which rely on partial positive feedback to enhance the effective transconductance of a CMOS bulk-driven input stage, thus leading to improved values for the DC gain and the gain-bandwidth product. The first approach modifies the conductance of the active load, while the second solution acts directly ...

0.8V bulk-driven variable gain amplifier

2010 17th IEEE International Conference on Electronics, Circuits and Systems, 2010
A low-voltage variable gain amplifier based on PMOS bulk-driven input stage is presented in this paper. The gain of the proposed amplifier has a linear in-dB gain dependency since it utilizes the conventional pseudo exponential approximation function (1+x)/(1−x). The master-slave technique is used in order to control the voltage gain.

Bulk-Driven Current Differencing Transconductance Amplifier

Circuits, Systems, and Signal Processing, 2011
Low-voltage (LV) low-power (LP) integrated circuit design is becoming a leading trend in VLSI technology, particularly in special portable applications. In this paper, the principle of a bulk-driven MOS transistor is employed in the design of a novel LV LP current differencing transconductance amplifier (CDTA).

Low-voltage bulk-driven mixer with on-chip balun

2008 IEEE International Symposium on Circuits and Systems (ISCAS), 2008
The design and simulation of a pair of bulk-driven low-voltage down-conversion mixers with on-chip transformer baluns is presented. The addition of a passive balun improves gain and can provide impedance matching for optional off-chip image-reject filters.

0.4-V bulk-driven differential-difference amplifier

Microelectronics Journal, 2015
A new solution for an ultra-low-voltage, low-power, bulk-driven fully differential-difference amplifier (FDDA) is presented in the paper. Simulated performance of the overall FDDA for a 50nm CMOS process and supply voltage of 0.4V, shows dissipation power of 31.8µW, the open loop voltage gain of 58.6dB and the gain-bandwidth product (GBW) of 2.3MHz for

Comparative Performance Study of Multiple-Input Bulk-Driven and Multiple-Input Bulk-Driven Quasi-Floating-Gate DDCCs

AEU - International Journal of Electronics and Communications, 2019
Abstract This brief presents a comparative performance study of two recently presented techniques, the multiple-input bulk-driven (MI-BD) and the multiple-input bulk-driven quasi-floating-gate (MI-BD-QFG) MOS transistors (MOST). These techniques offer simplified CMOS structures of specific active elements and ensure near rail-to-rail operation ...

Extremely Low-Voltage Bulk-Driven Tunable Transconductor

Circuits, Systems, and Signal Processing, 2016
A design solution for bulk-driven tunable transconductor capable of working under extremely low supply/consumption with rail-to-rail input common-mode range is presented in this work. The proposed transconductor topology consists of six bulk-driven CMOS inverters, and it uses a very simple biasing circuit for the transconductance tuning.

Utilizing the Bulk-driven technique in analog circuit design

13th IEEE Symposium on Design and Diagnostics of Electronic Circuits and Systems, 2010
The last few decades, a great deal of attention has been paid to low-voltage (LV) low-power (LP) integrated circuits design since the power consumption has become a critical issue. Among many techniques used for the design of LV LP analog circuits, the Bulk-driven principle offers a promising route towards this design for many aspects mainly the ...

A low voltage bulk driven downconversion mixer core

ISCAS'99. Proceedings of the 1999 IEEE International Symposium on Circuits and Systems VLSI (Cat. No.99CH36349), 2003
This paper describes a CMOS mixer core, operating at 1 GHz, where the RF signal is input via the bulk. The advantages of a bulk driven mixer are low power supply voltages and low power consumption. Simulations have confirmed that a power supply as low as 1 V can be used to power the mixer core, which drains approximately 1.6 mA. Although the mixer core

Modeling and design of a Folded Cascode bulk driven OTA

7th International Conference on Design & Technology of Integrated Systems in Nanoscale Era, 2012
Analog 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,
