The first FPGA multiple channel digital-to-time converter, or digital pulse generator, is proposed to further extend FPGA applications into analog domain. Based on vernier principle, the effective resolution is made equivalent to the period difference of two phase-locked loop (PLL) outputs. The finer than ever DTC resolution of 1.58 ps is achieved with an Altera Stratix III FPGA chip. The DNL and INL are verified to be -0.086 ~ +0.12 LSB and -0.93 ~ +0.75 LSB respectively for input value varied… CONTINUE READING
