Abstract

Aiming at the requirement of large-scale switch synchronous triggering in all-solid-state linear transformer driver (LTD), this paper designs a new dual-channel synchronous high-resolution digital-to-time converter (DTC) based on the vernier method and pre-phase shift technology. On the basis of the original vernier DTC, the relationship between the overlapping positions of different generated pulse phases is calculated in advance, and the clock signal meets the phase relationship in advance through phase shift and phase detection, so as to achieve the purpose of triggering multiple pulse signals of different widths at the same time. The realization principle and circuit design module of DTC are expounded in detail, and the simulation and Field Programmable Gate Array (FPGA) realization are carried out. At the same time, the realization result is tested, analyzed and discussed. On the Xilinx ARTIX-7 FPGA development board, the resolution of the first pulse signal is 0.85 ps, and the differential nonlinearity (DNL) and integral nonlinearity (INL) are −2.55～2.17 LSB and −7.33～7.05 LSB, respectively. The resolution of the second pulse signal is 17.1131 ps, DNL and INL are −0.005～0.0105 LSB and −0.299～0.288 LSB respectively, and the performance of DTC can still be guaranteed in the ambient temperature of 0～80 ℃. The results show that this DTC has the advantages of simple implementation, low cost and high performance.
