Abstract :
This paper presents a new technique to reduce the conversion time, hence improve the throughput, of the two-stage Time to Digital Converter (TDC) architecture. An oscillator based TDC is used in the first and second stages. The time residue from the first stage is generated directly after the stop signal is asserted and saved in the form of phase-shift between two oscillating signals. A throughput of 400 MS/s, a DNL of 0.38, and an INL of 0.36 are achieved.
