Keywords: | Biomedical electronics; Capacitive transducers; Pressure sensors; Thyristor circuits | Issue Date: | Oct-2019 | Source: | Biomedical Circuits and Systems Conference (BioCAS): 8919042 (2019-10) | Abstract (english): | This work presents a Capacitance-To-Digital Converter for in-vivo pressure monitoring in clinical scenarios. The developed system combines a Capacitance-To-Time Converter (CTC) and a Time-To-Digital Converter (TDC), of which the CTC presents a novel architecture based on CMOS Thyristor elements with a power consumption of only 2.99 μW. The interface was implemented in a 350 nm CMOS technology and tested in combination with a commercially available capacitive pressure transducer. The Capacitance-To-Time Converter unit achieves an average pressure resolution of 0.30 mmHg while consuming 4.19 pJ/conv. |
