MULTICHANNEL READING DEVICE BASED ON CHARGE COUPLING UNITS Russian patent published in 1995 - IPC

FIELD: integral microelectronics. SUBSTANCE: common writing wire and preliminary processing unit having signal input and compensating output are introduced to accomplish the goal of invention. In addition each channel has three gates, diffusion area which type of conductance is opposite to substrate and field-effect transistor. additional diffusion area is connected to second input gate through first additional gate, second and third additional gates are inserted between second input gate and transfer gate and there is charge coupling additional gates to transfer gate. Drain of additional transistor is connected to second additional gate, its gate is connected to corresponding input of commutator, its source is connected to common writing wire, signal input of preliminary processing unit is connected to common reading wire, its compensating output is connected to common writing wire. EFFECT: increased precision of suppression of signal components carrying no information. 1 dwg
