Technical details and manufacturing context for Time-to-Digital Converter (TDC)

Definition
A Time-to-Digital Converter (TDC) is a critical component within Timing Electronics systems. It precisely measures the time difference between a start signal (e.g., a laser pulse) and a stop signal (e.g., a photon detection event) and outputs this interval as a digital value. Its primary role is to provide high-resolution timing measurements, enabling applications like time-of-flight calculations, laser ranging (LiDAR), positron emission tomography (PET), and high-energy physics experiments.
Working Principle
A TDC operates by using a high-frequency reference clock or a delay line. In a delay-line TDC, the start signal propagates through a chain of delay elements. The stop signal captures the state of these elements, and the position where the start signal has reached is encoded into a digital word, representing the measured time interval. Other architectures use vernier delay lines, time amplification, or interpolation between clock edges to achieve sub-gate-delay resolution.
Common Materials
Silicon (for integrated circuits)
Technical Parameters
  • Time resolution, representing the smallest time interval the TDC can distinguish (e.g., 10 ps). (ps) Customizable
Components / BOM
  • Delay Line
    Creates a series of precise time delays for the start signal to propagate through.
    Material: Integrated circuit elements (transistors, capacitors)
  • Capture Register (e.g., D Flip-Flops) Part
    Latches the state of the delay line at the moment the stop signal arrives.
    Material: Silicon
  • Encoder
    Converts the parallel output of the capture register into a binary digital code representing the measured time.
    Material: Silicon (logic gates)
  • Control Logic
    Manages the start/stop signal handshake, reset, and data output sequencing.
    Material: Silicon
