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.
