摘要： A charge-coupled device has a transversal filter portion (10) having split sensing electrodes 1109, 113, 117, 121, 125) whose segments (A, B) are connected to respective output lines(SE 1 , SE 2 ), and an auxiliary portion (20) which has one or more auxiliary split sensing electrodes (209) whose segments (A. B) are respectively connected to the same output lines (SE 2 , SE 2 ). There are many more sensing electrodes in the filter portion (10) than in the auxiliary portion (20). In use, signal-independent charge packets are transferred along the channel in the auxiliary portion to provide a controllable offset signal. which can be used to provide a controllable threshold for tone detection. There may additionally be a dummy portion (30) to balance the capacitative loading of the output lines (SE 1 , SE 2 ) by the auxiliary electrodes (209).
