Abstract
Provided are a TDC having a pipeline or cyclic structure and an operating method thereof. The TDC includes a first stage block and a second stage block. The first stage block detects a first bit of a digital code for a time difference between first and second input signals. The second stage block detects a second bit of the digital code for a time difference between first and second output signals of the first stage block. The first stage block amplifies a time difference between first and second delay signals for the first and second input signals to generate the first and second output signals, and transfers the first and second output signals to the second stage block.
