Recursive filters with a common channel charge transfer device
Abstract:
A common channel charge transfer recursive filter has two delay lines, in which charges are transferred in opposite directions. Exchange bridges having two sections extend between the lines. Each section feeds a predetermined charge fraction to one of the two downstream electrodes with charges flowing from the two upstream electrodes. The charge transfer is controlled by a three-phase system (.phi.1, .phi.2, .phi.3). Split memory electrodes and the exchange bridges are connected to the first phase (.phi.1) bus. A transfer electrode is in each gap between an exchange bridge and a memory electrode and is connected to the second phase (.phi.2) bus. A second transfer electrode is connected to the third phase (.phi.3) bus. The gap between a memory electrode and the next exchange bridge is occupied by a transfer electrode connected to the second phase (.phi.2) bus and by a transfer electrode connected to the third phase (.phi.3) bus.
