FPGA APPARATUS AND METHOD OF THE SAME OF SENSING TEMPERATURE BASED ON FIELD-PROGRAMMABLE GATE ARRAY

摘要

The present invention relates to an FPGA-based temperature sensing device and a sensing method, and a temperature sensing device according to an embodiment includes a frequency divider for generating an external clock frequency (T _REF ) _divided from an external clock (CLK ₂₀₀ ) (R-OSC) using a reference temperature (T _C) reference clock frequency (T _{PTAT @ C)} an oscillation unit for outputting, and an external clock frequency, the generated (T _REF) and the output reference clock frequency corresponding to the ( T _PTAT to withstand _{@ C)} generates the reference value (PW _PTAT), and can on the basis of the generated reference value (PW _PTAT) to a control unit for correcting an offset of the ring oscillator (R-OSC).
