Abstract

We propose an alternative approach for time interpolation of TDC in which a saw-tooth wave is generated instead of using sinusoidal wave in [10]. The proposed approach avoids floating number operation as well as lowers the dependency on analog passive components. Since the differential portion of two projected signals is amplified in the interpolation circuit, the wider range of time interval can be measured while preserving a few picoseconds resolution. It is also expected that the computational burden of DSP is decreased as well as its repeatability is enhanced. Compared with the conventional analog interpolation approach, the proposed saw-tooth based interpolation TDC overcomes the drawbacks of conventional analog interpolation TDC by reducing the dependency on passive components which are sensitive to environment and operational conditions. It provides high repeatability and linearity property within a wide range of operation with high resolution of measurement. With the aid of proposed interpolation circuit, a practical TDC and its embedded measurement system are expected to be implemented. The experiment results demonstrate its feasibility and effectiveness for practical usage with a simple and low cost implementation.
