AI Article Synopsis

  • The report introduces a fully adjustable arbitrary timing generator (ATG) utilizing a multistage time interpolation method, achieving a precise timing adjustment resolution of 3 picoseconds (ps).
  • The ATG features an adjustable output signal amplitude, controlled by a current module, allowing flexibility in output voltage from -1 to +5 volts.
  • It demonstrates a short-term jitter of 3.2 ps and supports a pulse width dynamic range between 6.25 nanoseconds and 5 seconds, making it suitable for high precision timing control applications.

Article Abstract

We report a fully adjustable arbitrary timing generator (ATG) that is based on a multistage time interpolation method. A 3 ps timing adjustment resolution is achieved using a three-stage time interpolation module. The output signal amplitude of the ATG is adjustable, as a current controlled output module is designed to adjust the output voltage of driver circuits. A field programmable gate array is used to realize the main logic of the ATG. A 3.2 ps short term jitter, a pulse width dynamic range from 6.25 ns to 5 s, and an output voltage range between -1 and +5 V are obtained. The arbitrary timing generator can be used in the applications that require high precision timing control and adjustable output capacity.
