Abstract
This paper presents a noise resistant, auto calibrated all digital temperature sensor for circuit protection applications. The sensor uses a variable pulse-based design, allowing one-temperature-point calibration, significantly reducing time and costs for mass production and deployment. Since a digital temperature sensor is meant to serve an auxiliary role alongside a main circuit, the sensor is designed to filter out the noise and retain accuracy while an RSA circuit is encrypting. The proposed digital temperature sensor and RSA circuit are implemented on a Field Programmable Gate Array and tested using a temperature controlled chamber. The result is a low cost, low power temperature sensor resistant to noise and suitable for quick deployment in digital devices.
