Abstract

See full text

The present disclosure provides a differential clock cross point detection circuit and a detection method. The detection circuit includes: a first MOS transistor (M1), a second MOS transistor (M2) and a capacitor (C); a drain of the first MOS transistor (M1) is connected to a negative terminal (CLK−) of a differential clock, a gate of the first MOS transistor (M1) is connected to a positive terminal (CLK+) of the differential clock, and a source of the first MOS transistor (M1) is connected to a drain of the second MOS transistor (M2); a gate of the second MOS transistor (M2) is connected to the negative terminal (CLK−) of the differential clock, and a source of the second MOS transistor (M2) is connected to an output terminal through a node; one terminal of the capacitor (C) is connected to a node (A), and the other terminal of the capacitor (C) is grounded.
