Título: | A self-calibration circuit for a neural spike recording channel |
Autor: | Rodríguez-Pérez, Alberto CSIC ORCID; Ruiz Amaya, Jesús CSIC; Delgado-Restituto, Manuel CSIC ORCID; Sawan, M.; Rodríguez-Vázquez, Ángel CSIC ORCID | Fecha de publicación: | 2011 | Editor: | Institute of Electrical and Electronics Engineers | Citación: | IEEE Biomedical Circuits and Systems Conference (BioCAS): 464-467 (2011) | Resumen: | This paper presents a self-calibration circuit for a neural spike recording channel. The proposed design tunes the bandwidth of the signal acquisition Band-Pass Filter (BPF), which suffers from process variations corners. It also performs the adjustment of the Programmable Gain Amplifier (PGA) gain to maximize the input voltage range of the analog-to-digital conversion. The circuit, which consists on a frequency-controlled signal generator and a digital processor, operates in foreground, is completely autonomous and integrable in an estimated area of 0.026mm2, with a power consumption around 450nW. The calibration procedure takes less than 250ms to select the configuration whose performance is closest to the required one. | URI: | http://hdl.handle.net/10261/83838 | DOI: | 10.1109/BioCAS.2011.6107828 | Identificadores: | doi: 10.1109/BioCAS.2011.6107828 isbn: 978-1-4577-1469-6 |
