Vaegae Naveen Kumar, Member, IEEE, Venkata Lakshmi Narayana Komanapalli, Member, IEEE, Annepu Bhujangarao, and Samickannu Sankar reply on the sensitivity value for the three thermistors under study which is mistakenly presented as 5 kHz/°C. After intense review of experimental data of the technique, the values of sensitivity are obtained as 0.128 kHz/°C, 0.161 kHz/°C and 0.719 kHz/°C for the thermistor-1, thermistor-2 and thermistor-3 respectively in the temperature range 0-100/°C. The sensitivity value for the thermistor-2 is 0.162 kHz//°C in the range 15-85 /°C and for thermistor-3 is 0.714 kHz//°C in the range 20-70/°C. The theoretical and experimental results must be close to each other when experimental components are used with their designed specifications. The authors suggest amendment in The sensitivity of approximately 0.336 kHz//°C is achieved over a temperature range of 0 /°C-100/°C using the ANN-based linearization technique.

This paper presents the development of an artificial neural network (ANN)-based linearization technique for the voltage controlled oscillator (VCO) thermistor circuit. VCO thermistor circuit exhibits a linear analog temperature-frequency relation over a temperature range of 0 °C-100 °C with good response and reasonable error. An ANN-based direct modeling technique is used for a nonlinearity estimation of VCO thermistor circuit to further improve the linearity. The performance of the developed technique has been experimentally verified. A linearity of approximately ±0.2% and sensitivity of 5 kHz/°C are achieved over a temperature range of 0 °C-100 °C, with a high thermal stability. A notable feature of the developed technique is linearity and sensitivity of the temperature measurement, which are quite high. The efficacy of the technique is established through simulation studies and its practicality is demonstrated on a prototype unit. © 2001-2012 IEEE.
