—This paper reports two multitransducer vacuum-sealed capacitive barometric pressure sensors, one using single-lead and the other using multiple-leads to transfer the electrical signal out of the vacuum-sealed reference cavity. The first device operates with a resolution of 37 mtorr over a pressure range from 600 to 800 torr. The sensitivity is 27 fF/torr(More)
—This paper reports a mixed-voltage mixed-signal chip for interfacing multiple capacitive transducers to embedded processors in integrated microsystems. A programmable switched-capacitor readout circuit accommodates capacitive sensors from 16 fF to 40 pF and allows self-test and online calibration. The 20 mm 2 chip has a sensitivity of 1.25 mV/fF and is(More)
Nonsteroidal antiinflammatory drugs have been widely used for the management of inflammation, pain and nociception. Gastric intolerance caused by most of the nonsteroidal antiinflammatory drugs used today restricts their use. Several approaches have been proposed to modify the parent nonsteroidal antiinflammatory drugs molecule in order to reduce their(More)
