RANDOM NUMBER GENERATION CIRCUIT, RANDOM NUMBER GENERATION METHOD, AND ELECTRONIC DEVICE

Document Type and Number:

WIPO Patent Application WO/2021/142830

Kind Code:

A1

Abstract:

Provided are a random number generation circuit and method, and an electronic device. The random number generation circuit comprises: a pulse generation sub-circuit, configured to generate a plurality of pulses, wherein the frequency of the pulses varies with a change in environmental parameters; a frequency-locked loop circuit, wherein the frequency-locked loop circuit comprises a frequency-discrimination and phase-discrimination sub-circuit, configured to generate a phase relationship indicator signal and a frequency relationship indicator signal according to a phase relationship between an input signal and a feedback signal, the phase relationship indicator signal indicates whether the phase of the input signal is ahead of the phase of the feedback signal, and the frequency relationship indicator signal indicates a frequency magnitude relationship between the input signal and the feedback signal; a feedback sub-circuit, configured to generate the feedback signal according to the frequency relationship indicator signal and the frequency of the pulses; a seed generation sub-circuit, configured to generate a random number seed according to the phase relationship indicator signal; and a random number generation sub-circuit, configured to generate a random number sequence according to the random number seed.
