Time-of-flight sensor, distance measuring system, and electronic device

Abstract

The present application discloses a time-of-flight (TOF) sensor and a related chip, electronic device, and distance measuring system. The TOF sensor includes: a clock signal generation circuit to generate a first clock signal and a second clock signal; a transmission circuit to generate a third clock signal based on the first clock signal, wherein the third clock signal is outputted to the light-emitting module; a replicated transmission circuit to simulate the transmission circuit, and generate a fourth clock signal based on the second clock signal; a delay locked loop to generate a fifth clock signal based on one of sixth clock signals and the fourth clock signal; a clock tree to generate the plurality of sixth clock signals based on the fifth clock signal; a pixel array, having pixel columns respectively sampling the reflected light pulse based on the plurality of sixth clock signals to generate a sampling result.
