<p>A sensing arrangement for sensing charged particles and/or quanta of elektromagnetic radiation has a sensor device (12) and amplifier circuitry (14). The sensor device (12) provides a sensor signal to an imput mode (vin) of the amplifier (14) to cause the level at the amplifier output mode (vout) to change. A negative feetback device (T1) responds to the change in level of the output node (Vour) to vary the feedback effect to increase the loop again of said amplifier circuitry (14). A current mirror (T2,T3) resets the input node (vin) to its initil level. Single particle and integrating sensor arrangements are disclosed.</p> |
