Abstract
The disclosed high-performance time-to-digital converter (TDC) incorporates ratiometric signal quantization with correlated double sampling (CDS). The TDC includes an input voltage circuit that outputs an input voltage signal and a fractional reference voltage circuit that outputs a fractional reference voltage signal. The TDC also includes a quantizer circuit that provides a differential output of the input voltage signal and the fractional reference voltage signal as a digital time value. Various other methods, systems, and computer-readable media are also disclosed.
