摘要： A preamplifier stage with dynamically controllable signal gain in a data signal processing circuit that includes a downstream analog-to-digital signal converter. The level of the data signal subsequent to its preamplification is monitored and the gain of the preamplifier stage is dynamically adjusted in response to such data signal transcending one or more predetermined thresholds. Hence, the effective dynamic range of the preamplifier stage is extended, thereby also effectively extending the dynamic range of the overall system beyond that to which it would have otherwise been limited by the dynamic range of the analog-to-digital signal converter. In accordance with a preferred embodiment of the invention, such a preamplifier is used in an X-ray imaging system such as that using flat panel solid state imaging devices.
