| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A pulse-shrinking Time-to-Digital Converter (TDC) with an offset pulse width detection scheme is presented. In the conventional pulse-shrinking TDCs, the pulse-shrinking rate, which is defined as a pulse width change through a single pulse-shrinking buffer (PSB), is supposed to be constant. However, when the pulse width is narrow, the shrinking rate actually is not constant. This causes a non-linearity of TDCs. In order to avoid this issue, we propose an offset pulse detection scheme for the pulse-shrinking TDC that is composed of a ring of PSBs. The input time difference is converted to a pulse along with a fixed offset width. This pulse width keeps shrinking while it propagates on the PSB ring, then the conversion process finishes when the pulse width is shrunk below the original offset pulse width. If we chose a sufficient offset pulse width, the pulse shrinking rate remains constant during the time-to-digital conversion process. The proposed TDC is designed with 0.18$mu$m CMOS process and 3.8MS/s, 1.8ps time resolution with +1.3/-0.9LSB DNL and +2.5/-3.0LSB INL is verified by post-layout simulation. Its layout area and power consumption are 0.07mm$^2$ and 4.6mW, respectively. | |
