Description

The invention relates to the field of automation and can be used, for example, in information processing devices.

The aim of the invention is to simplify the device.

FIG. 1 shows a functional diagram of the device; in fig. 2 - timing charts of the device.

The device contains a ruler 1 of charge delay elements 2, a key 3, a double correlated sample block 4, a comparator 5 and a pulse counter 6, a device information input 7, an information signal input control input 8, an information signal output control input 9, inputs 10 charge transfer control, input 11 Reset, inputs 12 and 13 of a double correlated device sampling, device threshold input 14, device initial setup input 15, device information input 16, outputs 17c 18 blocks of double correlated selection orcs and comparator.

The device works as follows.

At time ti, a blocking potential is applied to input 8, the device is in standby mode. At time t2, the potential at input 8 is lowered, and the input signal is recorded in the input cascade. At time t3, the device is locked at input 8. At time points, alternating locking potentials are fed to the charge transfer control inputs 10 and the charge from input device 2 is transmitted to output device 2 with charge connection. At time ts, a signal appears at the output of the ruler on devices with charge coupling proportional to the input signal at time ti. This signal is controlled by

The signals at inputs 12 and 13 of the device are 4-terminated at the information input of the comparator 5. If the level of the threshold signal at input 14 is lower, then the output 18 of the comparator 5 is the potential to allow the counter 6, which was previously reset to input 15.

At time tg, a voltage pulse is applied to the input 9 of the device, over which a unit is written to the output stage, and the charge from the output charge region flows into the previous one.

At the next time point tio, the pulse at control input 9 ends and the charge again passes to the output stage of the ruler. In the process of such recharges, the charge decreases each time due to losses, for example, due to surface capture, and therefore decreases, and the output signal becomes after a certain number of cycles less than the threshold at the input of the comparator 5. This leads to the prohibition of counting in the counter 6. The number of recharges in the output stage, fixed in counter 6, will be proportional to the input signal and have a digital form, convenient for further processing.

Thus, due to the introduction of the counter 6 and the corresponding control of the operation of the device using simple means, the input signal is transmitted with a predetermined delay and converted into digital form.
