The FVF might be influenced by object-based attention

Behavioral and Brain Sciences, 2017
AbstractHulleman & Olivers (H&O) argue that the primary unit in search should be fixations, and in doing so posit a Functional View Field (FVF). There is evidence from the object-based visual attention literature that the FVF may not process visual information uniformly.

Gaze-contingent manipulation of the FVF demonstrates the importance of fixation duration for explaining search behavior

Behavioral and Brain Sciences, 2017
AbstractHulleman & Olivers' (H&O's) model introduces variation of the functional visual field (FVF) for explaining visual search behavior. Our research shows how the FVF can be studied using gaze-contingent displays and how FVF variation can be implemented in models of gaze control.

On the analysis of low output impedance characteristic of flipped voltage follower (FVF) and FVF LDOs

2017 IEEE 60th International Midwest Symposium on Circuits and Systems (MWSCAS), 2017
The flipped voltage follower (FVF), a variant of the common-drain transistor amplifier, comprising local feedback, finds application in circuits such as voltage buffers, current mirrors, class AB amplifiers, frequency compensation circuits and low dropout voltage regulators (LDOs). One of the most important characteristics of the FVF, is its low output

A FVF based output capacitorless LDO regulator with wide load capacitance range

2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013
An output capacitorless low-dropout (LDO) regulator, which applies the proposed Dual Summed Miller Frequency Compensation (DSMFC) on Flipped Voltage Follower (FVF) structure with composite power transistor, is proposed. Validated by UMC 65nm CMOS process, the simulation results have shown that the proposed LDO regulator consumes only 13.2μA at a 1.2V ...

An Empirical Correlation for Oil FVF Prediction

Journal of Canadian Petroleum Technology, 1988
Abstract A new empirical correlation for predicting oil FVF at bubble point pressure is developed from 420 experimentally obtained oil FVF on 119 oil-gas mixtures collected from four different unpublished sources. When applied to all data, the newly developed correlation clearly out-performs the ...

A push-pulled FVF based output-capacitorless LDO with adaptive power transistors

Microelectronics Journal, 2017
An output-capacitorless low-dropout regulator (LDO) based on an evolved versions of flipped voltage follower (FVF) has been proposed and simulated in a commercial 0.18m CMOS process in this paper. To get over the tradeoff between power consumption against other important design parameters such as loop stability and fast response, the proposed LDO is ...

A fast transient LDO based on dual loop FVF with high PSRR

2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2016
In this work, the design of a dual loop flipped voltage follower (FVF) based low-dropout regulator (LDO) to achieve fast transient response is proposed for all-digital phase locked loop (ADPLL) in the RFID application. With the help of an additional reference generation loop in FVF LDO and the cascaded structure, high power supply rejection ratio (PSRR)

A New High Drive Class-AB FVF-Based Second Generation Voltage Conveyor

IEEE Transactions on Circuits and Systems II: Express Briefs, 2020
A new low-voltage low-power class-AB second generation voltage conveyor (VCII) is presented. The proposed circuit is based on an improved class-AB flipped voltage follower (FVF) designed by adding a simple negative feedback loop to the conventional class-AB circuit.

Low Power Transimpedance Amplifier (TIA) Using Bulk Driven FVF

2019 4th International Conference on Information Systems and Computer Networks (ISCON), 2019
In this paper a low power transimpedance amplifier is designed using Bulk driven flipped voltage follower- FVF. A bulk driven MOS is used as current source in FVF topology instead of normal current source. This change in FVF topology helps to execute class AB operation of FVF and thus gives symmetrical slew rate. This circuit works on power supply of 1.
