Electronic latch, a method for an electronic latch, a frequency division by two and a 4-phase generator

摘要

The present invention relates to an electronic latch circuit, a method, and a 4-phase generator. The electronic latch circuit comprises an output circuit comprising an output X, and an output Y. The electronic latch circuit further comprises an input circuit, comprising an input A, an input B, and a clock signal input. The input circuit is connected to the output circuit, and configured to select a state of the output circuit from the group of a first state, a second state, and a third state. The input circuit is further configured to select the first state upon detecting a high state on the input B, a transition on the clock signal input from a low state to a high state, and a low state on the input A, and that the electronic latch circuit is in the second state. The input circuit is further configured to select the second state upon detecting a high state on the input A, a low state on the input B, a low state on the clock signal input, and that the electronic latch circuit is in the first state; The input circuit is further configured to select the third state upon detecting a high state on the input A, a transition on the clock signal input from a low state to a high state, and a low state on the input B, and that the electronic latch circuit is in the second state. The input circuit is further configured to select the second state upon detecting a high state on the input A, a low state on the input B, a low state on the clock signal input, and that the electronic latch circuit is in the first state.
