Demand of CO2 gas sensors is expected to continue to increase in the foreseeable future, due to an increasing awareness of air pollution and fossil fuel emissions. A truly low cost and accurate NDIR sensor has the potential of greatly benefiting the environment by an increased human awareness due to CO2 measurements. In the objective to reach these goals, a CO2 sensor core on an ASIC needs to be investigated. In this study an ASIC prototype design is tested on an FPGA and evaluated towards logic resource requirements, power analysis and estimated cost impacts towards a full ASIC. The results show that a potential ASIC implementation would have a very small cost impact on a full system design if the use of a preexisting ASIC design is utilized. Using a manufacturing process of 180 nm, the total logic implementation would require between 0.54-0.76 mm2. The cost impact of such a logic area would be around $0.025 USD per chip. The power consumption of the logical part would also be very small when compared to the various analog components of a full system design.
