| titleOfInvention | A circuit for a time-to-digital converter, corresponding method, and lidar |
| abstract | The invention provides a circuit that can be used for a time-to-digital converter, comprising: a counting unit configured to start counting a synchronization clock signal after receiving a start signal, and output coarse counting information according to a first readout signal; a synchronization unit , configured to output the first readout signal to the counter according to the stop signal and the synchronization clock signal, and output the time residual signal of the first readout signal and the stop signal to the signal conversion unit; and the signal conversion unit configured to receive the time residual signal and the multiphase clock signal, and quantize the time residual signal based on the phase state of the multiphase clock signal to obtain fine count information. The circuit designed by the invention can realize a wide time measurement range and high precision, and is not limited by the process, and greatly reduces the chip area, static power consumption and inconsistency in circuit design. |
