ABSTRACT:
The sensing device for sensing a physical parameter such as radiation, temperature or the like, comprises an analogue sensor element sensitive for the physical parameter to be sensed and outputting an analogue signal and an analogue two-digital converter (ADC) having an MOS input stage for receiving the analogue output signal of the sensor element so as to convert the analogue output signal to a digital output signal.
