Patent ID: 8199849

Claim:
A data transmitting device transmitting data according to a delay insensitive data transmitting method, the data transmitting device comprising: a data transmitter configured to generate a request signal and a data signal, the data signal having a Non-Return-to-Zero (NRZ) format that is divided into a binary value 0 and a binary value 1 at a transition point of the request signal; and an encoder configured to receive the request signal and the data signal and output an output current signal based on the received request signal and data signal, wherein the encoder comprises: a data comparator configured to generate a delay data signal by delaying the data signal by a predetermined delay time, sample the data signal and the delay data signal using the request signal, and output the sampled data signal and an operation signal that is obtained by comparing the sampled data signal and the sampled delay data signal; and a voltage to current converter configured to output the output current signal having different current levels according to a logical combination of the sampled data signal and the operation signal.
