Abstract

一种集成电路和用于测量距离的系统。该集成电路(10)包括：发射器(11)，被配置为发射测距信号；信号输入通道(12)和基于开关电容阵列的信号采样电路(13)，信号输入通道(12)被配置为向信号采样电路(13)传递测距信号的回波信号对应的模拟电信号，信号采样电路(13)被配置为对模拟电信号进行采样，并存储模拟电信号的采样信号；模数转换电路(14)，被配置为对信号采样电路(13)存储的采样信号进行模数转换，以生成用于指示回波信号接收时间的数字电信号。基于开关电容阵列的信号采样电路(13)可以利用开关电容阵列存储采样信号，因此模数转换电路(14)无需实时地对采样信号进行模数转换，降低了系统对模数转换电路(14)转换速率的要求。
