Simple Digital Pulse Width Modulator Under 100 ps Resolution Using General-Purpose FPGAs

  title={Simple Digital Pulse Width Modulator Under 100 ps Resolution Using General-Purpose FPGAs},
  author={Daniel Costinett and Miguel Rodriguez and Dragan Maksimovic},
  journal={IEEE Transactions on Power Electronics},
This letter describes a very simple implementation of a digital pulse width modulator (DPWM) under 100 ps resolution in low-cost field-programmable gate arrays (FPGAs). The implementation is based on internal carry chains and logic resources which are present in most FPGA families. The proposed approach does not require manual routing or placement, consumes few hardware resources, and does not rely heavily on specialized phase-locked loop or clock management resources. A 50-MHz switching… CONTINUE READING
