Description

Technical field [0001] The present invention relates to the field of analog-to-digital conversion technology, in particular to an asynchronous clock generation circuit and an implementation method thereof. Background [0002] Analog-to-digital conversion technology is a technique that converts an analog signal into a digital signal. Signals that appear in the real world, such as light intensity signals, electrocardiogram signals, etc., appear in the form of analog signals, and if these signals need to be processed digitally, these signals are converted into digital signals. The circuit that implements this technology is called an analog-to-digital conversion circuit, and today's analog-to-digital conversion circuits are mostly implemented in the form of semiconductor integrated circuits. The structure of the mainstream semiconductor analog-to-digital conversion circuits include flash-flash, successive approximation, pipeline and Sigma-Delta, among which the successive approximat...
