Integrated, singlechip gas sensing signal chains simplify the system design by, for example, integrating the TIA (transimpedance amplifier) gain resistors or employing a digitaltoanalog converter as a sensor bias voltage source (as seen in Figure 2). Thanks to the signal chain integration, the measurement channel can be fully configurable through software to interface with many different ...

Answer (1 of 3): There are very few sensors that are digital. We usually just ‘digitize’ them as we put electronics to work on the analog value. Even RF has to come into the antenna as a frequency sine wave, which is analog. The antenna is therefore analog unless it is hit by lightning or pulsed ...
