A Low Jitter Double-Tailed Strong-Arm Latch Based Digital-to-Time Converter (DTC)

2020 27th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2020
Digital to time converters (DTCs) have recently become important in phase comparison path in low jitter fractional- $N$ phase-locked loops (PLLs). This paper proposes a simple technique to implement a DTC using the Schmitt trigger. The proposed DTC consists of a double-tailed Strong-Arm latch that acts as a comparator, unlike other DTCs that involve ...

A high resolution Time-to-Digital Converter (TDC) based on self-calibrated Digital-to-Time Converter (DTC)

2017 IEEE 60th International Midwest Symposium on Circuits and Systems (MWSCAS), 2017
Based on the parallel DTCs as delay cells, a 4-bit TDC with adjustable 0.7ps∼1.4ps resolution and 11ps∼22ps dynamic range is proposed in this paper. In this design, an extremely high resolution DTC is presented, achieving 15.6fs delay per LSB. By utilizing 16 DTCs which are adjusted to have the same time interval among two neighboring DTCs, a highly ...

A 12-bit digital-to-time converter (DTC) for time-to-digital converter (TDC) and other time domain signal processing applications

NORCHIP 2010, 2010
This paper describes a digital-to-time converter (DTC) architecture that can be used as a fine interpolator in a time-to-digital converter (TDC) or as an adjustable delay in clock deskewing, for example. The new architecture of the DTC achieves adjustable sub-ps-level resolution with high linearity in ns-level dynamic range.
