Abstract
The invention pertains to a charge transfer shift register provided with a device for voltage sensing using a floating-potential diode. Towards that end of the register which is located on the floating-potential diode side, the width of the charge transfer channel diminishes gradually and symmetrically with respect to the longitudinal axis of the register, and the electrodes have a shape which is all the more similar to that of a ring sector as they are close to the floating-potential diode. Thus, the path followed by the charges which leave it up to the floating electrode are made substantially uniform for each of these electrodes, whether the charges leave the electrode near the edges of the channel or near the longitudinal axis of the register.
