AC instrumentation amplifier for bioimpedance measurements

IEEE Transactions on Biomedical Engineering, 1993
We analyze the input impedance and CMRR requirements for an amplifier for bioimpedance measurements when considering the capacitive components of the electrode-skin contact impedance. We describe an ac-coupled instrumentation amplifier (IA) that, in addition to fulfilling those requirements, both provides interference and noise reduction, and yields a ...

An improved current mode instrumentation amplifier

Proceedings of Third International Conference on Electronics, Circuits, and Systems, 2002
A current mode instrumentation amplifier in CMOS technology, is presented. The circuit is based on the use of two second generation positive current conveyors and a current differential output stage. The device exhibits high common-mode rejection ratio which is gain unaffected in a wide frequency band.

Multichannel instrument amplifier

Measurement Techniques, 1962
The design of multichannel devices with a common intermediate amplifier provides a reduced measurement error and a considerable reduction in the amplifying elements, which in turn raises the reliability of the device and reduces its size and weight.

Instrumentation Amplifiers and Operational Floating Amplifiers

2011
With the definition of universal active devices in Chap. 1 we have seen that the operational floating amplifier (OFA) is the most universal active device, even more universal than the operational voltage amplifier (OVA), abbreviated to OA or OpAmp, because of its most wide usage. The OpAmp provides us with accurate output voltage control. Additionally,

A 1 V instrumentation amplifier

42nd Midwest Symposium on Circuits and Systems (Cat. No.99CH36356), 2003
This paper describes the design and the implementation of a 1 V instrumentation amplifier in a 1.2 /spl mu/m CMOS process with V/sub TN/=0.6 V and V/sub TP//spl ap/-0.8 V. The instrumentation amplifier has a peak-to-peak output signal swing of /spl plusmn/350 mV. It uses two 1 V opamps and a Norton amplifier.

A chopper dc instrumental amplifier

Measurement Techniques, 1987
Because of their low zero drift chopper, dc amplifiers [I, pp. 22-23] are widely used in measuring equipment. The ratio of the maximum cut-off frequency of such an amplifier to its modulation frequency must be carefully chosen since an increase of its carrier frequency magnifies the effect of high-frequency pulse noise on the output voltage [2] in ...
