Other Abstract

The invention relates to a high-speed and high-precision digital pulse generating circuit and a pulse generating method. Sequences of a programmable reference pulse and a variable pulse can be generated by utilizing the digital circuit; the pulse widths in various pulse sequences and the phase deviation between the pulse sequences can be adjusted through a precise timed step length; the circuit has a function of automatically calibrating the timed step length and can be adaptive to large-range temperature change and change influence of a power supply; the circuit is composed of a system clock input circuit, a register control circuit, a system clock pulse timer circuit, a ring oscillator pulse timing circuit, a logic unit delay pulse timing circuit and a pulse output circuit; the circuit has high speed and high precision; the generating circuit is realized full digitally; and the circuit is high in cost performance and can be used in the fields of electronic measurement, semiconductor test, radar control and high-precision industrial measurement and control.
