In the area of sensor signal conditioning my research interests include RC-to-digital converters, differential capacitive sensors, instrumentation amplifiers, controllable constant-power sources for thermal based sensor applications, analog-to-digital converters with nonlinear transfer characteristics, and self-balancing bridge circuits for resistance measurement in both CMOS and BiCMOS technologies. The main achievements in this area have been published in the following articles:
