Patent ID: 11882373

Abstract:
A matrix-array detector having: an array of pixels arranged in a matrix along rows and down columns, each pixel for generating a signal according to a physical effect; a signal generator for generating two clock signals that are phase-shifted relative to one another; and a row-addressing device including a shift register, the shift register including a plurality of stages arranged in a cascade, each stage for receiving, in alternation from one stage to another, one clock signal from the two clock signals, and delivering an intermediate output signal that takes a high value and a low value allowing the pixels of the row to be activated and to be deactivated, respectively. The signal generator is also for generating a third clock signal. The addressing device further includes a plurality of isolation circuits, each isolation circuit connected between each stage and the corresponding row of the matrix, for receiving the third clock signal, the isolation circuit also for delivering a selection signal for selecting the corresponding row of the matrix when the intermediate output signal and the third clock signal are at the high level.
