Abstract
Disclosed is a charge transfer device, like a transversal filter, having means for detecting if an amount of signal charge transferred from one stage to another falls within a dynamic range of the device. A charge transfer channel is so formed as to have first and second branched output ports. A signal charge transferred to the first output port is detected as an output signal supplied to a utilization circuit while an output voltage caused by a signal charge transferred to the second output port is compared with first and second reference voltages which correspond to first and second amounts of signal charges substantially determining upper and lower limits of the dynamic range of the device, whereby it is detected if the amount of the signal charge transferred is within the dynamic range or not. As a result of the detection when the signal charge amount is outside the dynamic range, the supply of the output signal to the utilization circuit is interrupted.
