چکیده
The results of comparative DC simulation tests confirm that a proposed modification to the feedback circuit of a Flipped Voltage Follower (FVF), to produce a type of ‘Folded’ Flipped Voltage Follower (FFVF), is capable of maximising the linear DC operating range for given values of supply rail voltage and operating current.

Improving Bandwidth of Flipped Voltage Follower Using Gate-body Driven Technique
In this paper, a new approach to enhance the bandwidth of flipped voltage follower is explored. The proposed approach is based on gate-body driven technique. This technique boosts the transconductance in a MOS transistor as both gate and body/bulk terminals are tied together and used as signal input. This novel technique appears as a good solution to merge the advantages of gate-driven and bulk...

This paper identifies a conventional flipped voltage follower (FVF) for high performance, low-voltage and low-power applications. This basic circuit is used as a voltage buffer, impedance matching and a level shifter. It presents more suppleness in contrast to the basic voltage follower as dc voltage level can be amended by varying aspect ratio of the MOS transistors. However, gain of the flipp...
