Random generator with phase detector

Abstract

The application concerns a phase detector (DF) for a random generator and a method for regulating the operation of the phase detector, constructed from a flip-flop (P), whose inputs and output (D, C, Q) constitute the inputs and output of the phase detector (i1-DF, i2-DF, o-DF). The essence of the phase detector is a special flip-flop design with balancing elements in both the master and slave stages and a series of inputs (lo1M, lo2M, lo1S, lo2S) enabling control of the flip-flop's operation, which is controlled by a compensation and regulation circuit (UKR), also connected to the flip-flop's inputs and output (D, C, Q). This solution allows for: regulation of the operation between the master and slave stages of the flip-flop, symmetrization of the operation of each stage of the flip-flop, calibration of the phase detector, compensation during operation, and power consumption regulation.It is possible to compensate for technological dispersion, change the position and size of the metastability window, reduce the recovery time and reduce the impact of phase noise, compensate for the impact of aging and mechanical work, or the impact of environmental factors.
