In this paper an approach is made to design the voltage based efficient fire sensor and for that reason we have used four different kinds of Stub Series Terminated Logic (SSTL)IO standards. Airflow and heat sink are main parameters while analyzing the thermal dissipation in the circuit. In this work we have taken two values for LFM i.e. 250, 500 and three profiles for heat sink are taken, these are low profile, medium profile and high profile. When the voltage sensor is operating at 1THz and LFM is 250 with low profile heat sink, junction temperature of SSTL135_DCI is reduced up to 5.12% 6.03% and 20.77% as compared to SSTL12, SSTL12_DCI and SSTL135_R respectively. Under same operating frequency and heat sink profile with LFM as 500, we are achieving 3.69%, 5.22% and 17.99% less junction power reduction in SSTL135_DCI with respect to SSTL12, SSTL12_DCI and S S TL135_Rrespectively. This design is implemented on Kintex-7 FPGA, XC7K70T device and −3 speed grades. In this work we have used Verilog as HDL and Xilinx ISE 14.6 as simulator.
