Abstract

The invention provides a signal receiving system and method based on an array type sensor and the array type sensor, and relates to the technical field of microelectronics. In the signal receiving system, a control unit generates a demodulated signal based on an electric signal generated by a signal receiving unit, and instructs the signal receiving unit to receive an external signal based on thedemodulated signal based on the generated demodulated signal. Through updating the demodulated signal, the control unit can control the signal conversion unit to update the signal receiving time sequence so as to change the receiving time length and / or the receiving starting time point. Therefore, the echo signal can be received with a narrower pulse width in a place closer to the position of theecho, the interference of background light is effectively suppressed, the signal-to-noise ratio of the received signal is effectively improved, and the ranging precision is improved.

Description

technical field [0001] The present disclosure relates to the field of microelectronic technology, in particular, to a signal receiving system and method based on an array sensor and the array sensor. Background technique [0002] With the development of microelectronics technology, array sensors such as image sensors are widely used to receive external signals such as optical signals and acoustic signals in various fields. Therefore, the signal receiving ability is an important performance index of array sensors. [0003] In the prior art, more signals can be received by increasing the area of ​​the array unit in the array sensor or prolonging the integration time of the received signal, but increasing the area of ​​the array unit will lead to a decrease in the number of array units in the array sensor. The measurement accuracy of the array sensor is reduced, and the extension of the integration time will result in receiving more target signals while receiving more reference...
