| Abstract: | The paper has introduced the technology of detecting flammable gases with double infrared wavelength lights. A logarithmic amplifier is needed for the detection. Considering the heavy influence of environment temperature on a logarithmic amplifier, a new circuit without logarithmic amplifier was developed. As a result, the reliability and sensitivity of the circuit are improved, and it is applicable to practice. |
