Offset error mechanisms in a single-ended chopper-stabilized amplifier are investigated.
The error models and their prediction equations are given. This work also presents a new …

A signal acquisition system is presented for the recording of small signals in the presence of
low-frequency interference. In a conventional design, high-pass filters precede the input …

The demand for health-monitoring products is increasing worldwide. Low-power and low-
voltage attributes are important concerns that need to be addressed in circuits used for …

This study outlines the potential use of a proposed tunable source degenerated telescopic
OpAmp for biomedical signal acquisition systems. Mathematical background is presented for …

Pain perception and its EEG wave have been used to describe the body's neural systemic
response with respect to a given stimulation. Pain artificially induced by non-coherent …

[ES] La deglución es un proceso complejo que involucra la coordinación de músculos
orofaciales y faríngeos. Las alteraciones de este proceso pueden tener consecuencias que …

A safe electrical connection between an integrated circuit and the human body is required
for the recording of physiological signals such as ECG, ENG, or EMG. The recording chip is …

The recording of small signals such as body potentials requires high-gain amplification. In a
high-gain system even small offset voltages pose a problem when they saturate the …

A new ultra low-power CMOS Electromyograph (EMG) amplifier is presented in this paper. It
is based on the application of a novel capacitive load reduction circuit technique to the …

A signal acquisition system is presented which is suitable for small signals in the presence
of low-frequency interference. In a conventional design filters precede the input stage to …
