Voltage mode transmitter

A voltage mode transmitter, comprising:

• a first control unit configured to receive a first signal and delay an inverse of the first signal for a time period to obtain a second signal;
• a first resistor ladder circuit configured to sum up products of the first signal or the second signal and a plurality of weights, thereby generating a first output signal;
• a second control unit configured to receive a third signal and delay an inverse of the third signal for the time period to obtain a fourth signal;
• a second resistor ladder circuit configured to sum up products of the third signal or the fourth signal and the weights, thereby generating a second output signal, the second resistor ladder circuit comprising:
• an output terminal configured to output the second output signal;
• a plurality of first resistors each of which is electrically coupled between the output terminal and the second control unit, and receives the third signal or the fourth signal, wherein resistance values of the first resistors are 2R, 4R . . . and 2nR respectively, where R is a reference;
• and
• a second resistor electrically coupled between the output terminal and a ground terminal, wherein a resistance value of the second resistor is 2nR, where n is a positive integer greater than 1.
