摘要： A time-to-digital converter includes low and high resolution time-to-digital converters for providing both high resolution and wide measurement range. The low resolution time-to-digital converter measures a time difference between first and second signals with a first quantization step. The high resolution time-to-digital converter measures the time difference between the first and second signals with a second quantization step that is smaller than the first quantization step. The low resolution time-to-digital converter has a wider measurement range than the high resolution time-to-digital converter

摘要： A time-to-digital converter includes a first delay line, a second delay line, comparators, and an encoder. The first delay line includes first resistors coupled in series and receives a first signal through a start node. The second delay line includes second resistors coupled in series and receives a second signal through a node corresponding to an end node of the first delay line. The comparators compare first voltages of nodes on the first delay line with second voltages of corresponding nodes on the second delay line. The encoder generates a digital code based on outputs of the comparators. Therefore, the time-to-digital converter may decrease a chip size thereof and lower power consumption, and the time-to-digital converter may increase a range of a maximum delay time between two signals.
