Abstract
An oversampling circuit and method is proposed, which is used for converting an input serial data stream into a parallel data format. The proposed oversampling circuit comprises an array of transmission gates arranged into N cascaded stages of main sampling circuits, each stage of main sampling circuit being composed of M parallel layers of sub-sampling circuits, where N, M are each an integer number; each transmission gate has an input end, an output end, and a control port; and the respective control ports of all the transmission gates are connected to a predefined sequence of sampling pulses. The proposed oversampling circuit is characterized in that in the next stage of main sampling circuits, at least one of the transmission gates in one layer of sub-sampling circuit has its output end connected to one of the transmission gates in the next layer of sub-sampling circuit; and at least one of the transmission gates in the last layer of sub-sampling circuit has its output end connected to one of the transmission gates in the first layer of sub-sampling circuit. This arrangement can help reduce the number of fan-outs and allows a greater error margin that allows the pulse generation and sequencing to be easier to realize than the prior art.
