Abstract

This paper present the high resolution time-to-digital converter(TDC) using the new delay time measurement circuit. To generate tick mark on the time axis, the coupled oscillator, ORIGAMI, is used for precise scale marks. The minimal scale mark of the proposed method is ticked by the multiphase oscillator ORIGAMI, then the high resolution T-to-D conversion can be realized. The proposed TDC output is coded by the specific code, which is called as the center of gravity code, CGC. The CGC to binary decoding scheme is also discussed. To verify the proposed TDC performance, SPECTRE simulation results are shown, where 0.18 μm 1-poly 4-metal CMOS process is used.
