Abstract
An apparatus and a method. The apparatus includes a delay processor, a coarse converter and node selector connected to the delay processor and configured to select a first voltage V1 and a second voltage V2 of opposite polarities of adjacent stages of the delay processor, a fine converter connected to the coarse converter and node selector and configured to determine a zero-crossing time associated with the first voltage V1 and the second voltage V2; and an encoder connected to the coarse converter and the fine converter and configured to receive and encode the first voltage V1, the second voltage V2 and the zero-crossing time, wherein V1 is a first negative voltage before the zero-crossing time, and V2 is a first positive voltage after the zero-crossing time.
