Design of a CMOS readout circuit on ultra-thin flexible silicon chip for printed strain gauges

Abstract: Abstract. Flexible electronics represents an emerging technology with features enabling several new applications such as wearable electronics and bendable displays. Precise and high-performance sensors readout chips are crucial for high quality flexible electronic products. In this work, the design of a CMOS readout circuit for an array of printed strain gauges is presented. The ultra-thin readout chip and the printed sensors are combined on a thin Benzocyclobutene/Polyimide (BCB/PI) substrate to form a Hybrid… Show more

“…Depending on the input stage type (NMOS or PMOS), the ability of the CFIA to amplify sensors' voltages that approach either of the CFIA supply rails makes it suitable to condition universal types of sensors and measurements, e.g., current sensing measurements [140,141], strain gauges [142], biomedical signals interface [139], micro-electromechanical systems (MEMS) interface [143,144], magnetic field sensor interface [27,145,146], electrical impedance spectroscopy (EIS) [147,148], etc. However, the CFIA suffers from two issues relevant to the DDF core amplifier; the first one is the gain inaccuracy error because of the mismatching between the input and feedback transconductance [140].…”
