Emerging RFID technology lets us embed sensors into a very small chip, creating a wireless sensing device. So, we set out to develop such a single-chip versatile temperature sensor. We also wanted to be able to transfer our design to an implantable t

In micromachined applications, the size of the sense capacitance is typically limited by the technology to a few hundreds femtofarads, thus resulting in a large sampling (kT/C) noise. This paper demonstrates that correlated double sampling (CDS), whi
