“…Besides, if chopping is used to decrease the influence of 1/f noise on the amplification chain, applying a chopping frequency of only 30 Hz to the amplifier presented in Section III.C will already be sufficient to meet the SNR required for EHG measurements. Another case study which is worth mentioning is Heart Rate (HR) monitoring during physical activities, described in [32]. In this kind of wearable application, the use of a flexible electronic frontend could be a very interesting option, for its potential of decreasing motion artefacts.…”

“…In this kind of wearable application, the use of a flexible electronic frontend could be a very interesting option, for its potential of decreasing motion artefacts. The authors of [32] use a Doubechies orthonormal wavelet to improve the detection rate of R-spikes present in the ECG signal. The algorithm is evaluated by analysing real signals with different SNR, from 36 dB to 6 dB, and the results show a correct detection rate of 94.8% on signals with 6 dB of SNR.…”

Three novel differential amplifier topologies using double gate a-IGZO TFTs on flexible substrate are presented in this paper. The designs exploit positive feedback and a load with self-biased top gate to achieve the highest static gain in single stage a-IGZO amplifiers reported to date. After fabrication, the three amplifiers exhibit respectively a static gain of 14 dB, 21.5 dB and 30 dB, with a bandwidth of 2 kHz, 400 Hz, and 150 Hz. Also, for each circuit the input referred noise has been measured to be 420 μVrms, 195 μVrms and 146 μVrms, respectively. Based on these results, the a-IGZO amplifier providing the highest gain is suitable as front-end for heart rate measurements and, with some further optimization verified in simulation, can also be used for other bio-potential applications, like electro hysterogram and electro cardiogram
