A rail-to-rail ping-pong op-amp
IEEE Journal of Solid-State Circuits, 1996A rail-to-rail ping-pong op-amp achieves offset cancellation and 1/f noise reduction without folding of the input spectrum. The clocking scheme minimizes the clock feedthrough and the residual offset due to charge injection. With a clock frequency of 100 kHz, the residual offset is less than 100 /spl mu/V, and the input referred noise is about 225 nV ...

The main goal of this work was to design an input stage which works rail-to-rail and have constant transconductance for the entire common mode range, and it was to be done without the necessity of matching p-and n-channel transistors. Two new circuits which possess these requirements were developed in the previous chapter; however, the effort will be ...

IEEE Journal of Solid-State Circuits, 1988
A CMOS op amp (operational amplifier) is reported which has a rail-to-rail voltage range at its input as well as its output. An area-efficient output stage has been used. While the entire op amp occupies only 600 mil/sup 2/, when used as a unity-gain buffer and with +or-5-V supplies, the op amp can drive a 9-V/sub pp//1-kHz sine wave across a 300 ...

A RAIL-TO-RAIL BUFFER AMPLIFIER FOR LCD DRIVER
Journal of Circuits, Systems and Computers, 2011A high-speed low-power rail-to-rail buffer amplifier, which is suitable for liquid crystal display driver applications, is proposed. An offset voltage is intentionally built in the second stage to cut off the transistors of last stage from the output node in the stable state and hence achieve low dc power consumption. The input referred offset voltage

This paper proposes an alternate switched-capacitor amplifier capable of handling rail-to-rail input common-mode voltage without using a rail-to-rail op-amp. Unlike most existing switched-capacitor architectures, the proposed alternate architecture holds the op-amp input terminals at a fixed voltage level in both the sample and hold phases irrespective

gm-Extraction for rail-to-rail input stage linearization
International Journal of Circuit Theory and Applications, 2005Summary: Transconductance of rail-to-rail input stages in low-voltage operational amplifiers depends on the presence of a large common mode input signal. Corrections must be implemented in order to correct it. Nevertheless, techniques actually used, based on switching or feedforward, still give relevant deviation from the constant transconductance ...

Experimental Results on Low Rail-to-Rail Conductance Values
IEEE Transactions on Vehicular Technology, 2005Measurement results concerning rail-to-rail conductance are presented, based on two measurement campaigns performed in Italy at Rigutino (AR) and Anagni (FR) in spring/summer 2003. Rails in the two sites are isolated from the sleepers and the earth and the weather conditions were hot and dry, so the measured conductance values represent a lower bound ...

Low‐voltage rail‐to‐rail switched buffer topologies
International Journal of Circuit Theory and Applications, 2001AbstractThis paper presents some CMOS rail‐to‐rail low‐voltage (1.2 V) switched buffer topologies, to be used as input stages in switched‐opamp circuits. The main buffer is based on the use of an op‐amp featuring rail‐to‐rail input and output swing with constant transconductance over the input common mode voltage.

A 1.75 V rail-to-rail CMOS op amp
Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002In this paper, a low voltage CMOS op amp, that can operate from a single 1.75 V supply voltage is presented. The op amp-has the capability of handling input signals exceeding both the positive and the negative supply rails. This is achieved by connecting n- and p-type differential pairs in parallel. The transconductance (g/sub m/) of the op amp is kept
