Abstract

Zgłoszenie dotyczy detektora fazy (DF) generatora losowego i sposobów regulacji pracą detektora fazy, zbudowanego z dwóch przerzutników (P1, P2) komplementarnie podłączonych do jego wejść (i1-DF, i2-DF) oraz elementów logicznych (AND, NOT, XNOR) dołączonych do wyjść przerzutników (Q1, Q2) i zamieniających pierwszeństwo na logiczne wartości oraz wykrywających wewnętrzny błąd detekcji. Wskutek błędu detektor utrzymuje na wyjściu (o-DF) stan ostatniej poprawnej detekcji dzięki zatrzaskowi (L), a błędy detekcji zapisywane są w rejestrze przesuwnym. Pracą przerzutników steruje układ kompensacji i regulacji (UKR), który dzięki specjalnej budowie przerzutników pozwala na: regulację szybkości jednego przerzutnika względem drugiego, regulację pracy między stopniem master i slave w każdym przerzutniku, równoważenie pracy każdego stopnia każdego przerzutnika, wzorcowanie detektora fazy, kompensację w trakcie pracy, czy regulację pobieranej mocy. Możliwa jest kompensacja rozrzutów technologicznych, zmiana położenia i rozmiaru okna metastabilności, regulacja wpływu szumu fazowego, redukcja czasu regeneracji, kompensacja wpływu starzenia się i pracy mechanicznej, czy oddziaływania czynników środowiskowych.The application concerns a phase detector (DF) for a random generator and methods for regulating the operation of the phase detector, constructed from two flip-flops (P1, P2) complementarily connected to its inputs (i1-DF, i2-DF) and logical elements (AND, NOT, XNOR) connected to the flip-flop outputs (Q1, Q2), converting priority to logical values and detecting internal detection errors. Due to an error, the detector maintains the last correct detection state at the output (o-DF) using a latch (L), and detection errors are stored in a shift register. The operation of the flip-flops is controlled by a compensation and regulation circuit (UKR), which, thanks to the special design of the flip-flops, allows for: speed regulation of one flip-flop relative to the other, regulation of the master and slave stages in each flip-flop, balancing the operation of each stage of each 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, regulate the influence of phase noise, reduce the recovery time, compensate for the influence of aging and mechanical work, or the impact of environmental factors.
