“…N EXT generation of Brain Machine Interfaces (BMIs) enable an accurate and precise recording of neural signals to treat neurological disorders as well as to advance neuroscience research [1]- [6]. Neural recording interfaces with an escalated spatio-temporal resolution is thus highly desired in comprehending various neural interactions such as thoughts, cognition, perception, and actions as well as in recovering neurological diseases such as stroke [7], Parkinson's disease [8], [9], Epilepsy [10], [11], Alzheimer's disease [11], Schizophrenia [12], etc. [13].…”

“…An efficacious neural recording system requires to meet the requirements of miniaturized area, minimum tissue damage (low power dissipation), high channel count, noise performance, wireless transmission, and system power consumption [8], [26]- [28]. A trade-off between the key requirements including the power and noise performances of the analog front-end is very critical in designing the neural signal recording system.…”

“…For the prolonged treatment of chronic diseases, a neural amplifier must fulfil several essential requirements. These encompass 1) a substantial input impedance, 2) minimal power usage to prevent tissue harm and optimize battery life [7], [8], [9], [10], 3) compact area for system miniaturization, 4) low-level of input-referred noise for accurate spike detection amidst background noise, 5) substantial common-mode rejection ratio, 6) elimination of DC voltage [11]. Furthermore, the need for electrode arrays with Fig.…”

“…On the other hand, there is an alternative method that blocks these DC offset voltages by using a low-pass filter in the feedback path, which is called DC-coupled input offset rejection. The authors in Enz et al (1995), Yazicioglu et al (2008), Muller et al (2012), Biederman et al (2013), Lee et al (2019), Jomehei and Sheikhaei (2019), Cabrera et al (2020), and Farouk et al (2020) use this method, however, it requires a huge capacitor or high power consumption amplifier in the feedback path.…”
