A low noise instrumentation amplifier
Journal of Physics E: Scientific Instruments, 1974Difficulty in obtaining very low noise difference amplification with gain stability using conventional operational amplifier circuitry is considered. A design procedure eliminating the incompatibility of gain stability and low noise is discussed. The design, circuit details and performance of low noise, high input impedance amplifier with good gain ...

Instrumentation Amplifiers and Operational Floating Amplifiers
2011With 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 0.01% linear instrumentation amplifier
1980 IEEE International Solid-State Circuits Conference. Digest of Technical Papers, 1980The use of combined resistive and current mode feedback in an instrumentation amplifier with 8nV/ \sqrt{Hz} input voltage noise, 2nA input bias current and 0.01% linearity will be reported. Laser trimming of silicon-chrome resistors affords 20μV input offset voltage and 0.2μV/°C drift.

CDBA based current instrumentation amplifier
Journal of Communications Technology, Electronics and Computer Science, 2016This paper presents a novel method to realize a current mode instrumentation amplifier (CMIA) through CDBA (Current difference Buffered Amplifier). It employs two CDBAs and two resistors to obtain desired functionality. Further, it does not require any resistor matching. The gain can be set according to the resistor values.

Yokto (10-24V) Instrumentation Amplifier
2012 Third International Conference on Computer and Communication Technology, 2012Operational amplifiers (op-amps) are the building blocks for analog signal conditioning circuits and in particular, instrumentation amplifiers. Op-amps amplify electrical signals such as the small voltages coming from instrumentation sensors. The gain is controlled by external components, provided the amplifiers are operated within reasonable ...

A chopper dc instrumental amplifier
Measurement Techniques, 1987Because 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 ...
