Claim 11:
12. The system of claim 11, wherein a supply voltage VDD1 to the third transistor is selected to correspond to a first given concentration of the gas, and a supply voltage VDD2 to the fifth transistor is selected to correspond to a second given concentration of the gas, which is larger than the first given concentration, so that (a) when the concentration of the gas is below the first given concentration, the inverter generates a 0 value and the additional inverter generates a 0 value, (b) when the concentration of the gas is above the first given concentration but below the second given concentration, the inverter generates a 1 value and the additional inverter generates a 0 value, and (c) when the concentration of the gas is above the second given concentration, the inverter generates a 1 value and the additional inverter generates a 1 value.
