In modern smart building climate control systems, accurate detection of unusual behavior in temperature sensors (outliers) can help reduce or prevent waste of energy consumption in a Heating, Ventilation and Air Conditioning (HVAC) system. In this work, we propose online learning-distance based outlier detection method. In the new method, we train and tune a multilayer neural network to learn a nonlinear...
An accurate, robust CMOS voltage reference biasedin subthreshold region with integrated temperature sensor circuit has been proposed in 180nm technology node using UMC RF process for IoT and low cost SoC applications. In UMC 180nm node the proposed reference voltage has an accuracy of 65 ppm/°C over 3σ variation in process and ±10% variation in supply, in the...
In this paper, we propose a cycle-accurate monitor that can efficiently detect timing violation based fault attacks. The proposed monitor detects clock or voltage manipulations by monitoring the external clock using an internal Ring Oscillator. The monitor is low cost in terms of area and power consumption and can be easily implemented using the standard cell based VLSI design flow. In addition to...
In this manuscript an area efficient, linear, robust CMOS integrated temperature sensor circuit has been proposed in multiple technology nodes using UMC RF process for IoT and low cost SoC applications. In UMC 180nm node the proposed temperature sensor has an accuracy of ±0.4°C over 3σ variation in process and ±10% variation in supply, in the temperature...
