Abstract

An Application Specific Integrated Circuit (ASIC) configured to control one or more gas sensors includes a light emitting diode (LED) driver which receives a pulse width modulator (PWM) signal for driving at least one ultraviolet (UV) LED, wherein an output of the at least one UV LED activates the one or more gas sensors; and an amplifier front end and an analog to digital converter (ADC) configured to calibrate an output of an amplifier to remove offsets associated with outputs associated with the one or more gas sensors, wherein calibration of the amplifier occurs after both generation of the PWM signal and entering a steady state by the one or more gas sensors in which the one or more sensors are not exposed to any gas but air and the amplifier receives one or more inputs associated with the one or more gas sensors.
