0.8V bulk-driven variable gain amplifier
2010 17th IEEE International Conference on Electronics, Circuits and Systems, 2010A 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, 2011Low-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), 2008The 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, 2015A 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

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), 2003This 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

Extremely Low-Voltage Bulk-Driven Tunable Transconductor
Circuits, Systems, and Signal Processing, 2016A 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.

A 0.5-V Bulk-Driven Active Voltage Attenuator
Circuits, Systems, and Signal Processing, 2019In this work, a novel differential active voltage attenuator that is capable of operating under low supply voltage and power consumption is presented. The proposed attenuator is based on bulk-driven MOS devices. Thanks to the use of the fully balanced differential structure, the attenuator demonstrates improved common-mode rejection capability.

A Bulk-Driven Lowpass Filter for EEG Signal
2020 6th International Conference on Engineering, Applied Sciences and Technology (ICEAST), 2020A typical Electroencephalography (EEG) acquisition system must include a lowpass filter (LPF) unit. According to the clinical applications, EEG signal have a conventional frequency range of 0.1-Hz to 70-Hz. The cutoff frequency for an LPF in EEG acquisition system should be in the same range.

Utilizing the Bulk-driven technique in analog circuit design
13th IEEE Symposium on Design and Diagnostics of Electronic Circuits and Systems, 2010The 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 ...
