We have demonstrated a chip-based diagnostics tool for the quantification of metabolites, using specific enzymes, to study enzyme kinetics and calculate the Michaelis-Menten constant. An array of 256×256 ion-sensitive field effect transistors (ISFETs) fabricated in a complementary metal oxide semiconductor (CMOS) process is used for this prototype. We have used hexokinase enzyme reaction on the...

The analysis of frequency-dependent characteristics of an ion-implanted buried-gate GaAs MESFET, with front side illumination has made achieving improved performance in I-V characteristics possible. When photo energy falls on the device, flow of charge carriers changes corresponding to the change in wave length and frequency of incident light. It has been observed that the channel conductance a...

In the recent years, hardware trojans have become a serious issue in the field of integrated circuits. Our work presents a framework for hardware trojan detection in wireless cryptographic integrated circuits. It deals with the leaking of secret information through a wireless communication, using a mixed-signal integrated circuit technique. A trojan is inserted in the introduced system, which d...
