Survey on Time –To- Digital Converter Architectures

P. Latha, Raveena Devi, V. Rajashree and Karbakaraksha

This paper presents the research issues on the development of Linear, Wide Dynamic range Time –To-Digital Converter (TDC) architectures with picosecond Resolution for precise measurement of time intervals. TDC architectures evolution from the basic counter based to pipelined architecture with calibration are analyzed. The timing resolution of a TDC directly determines the minimum resolvable spatial resolution in time-of-flight measurements. In TDCs, good linearity will provide high measurement accuracy, while the detectable range is limited by its dynamic range.
