A resistor network which utilizes modulating signals to modulate the resistance value of the individual resistive elements thereof. The resistor network includes a plurality of input terminals and output terminals, and a resistive element and a first switch connected in series with the resistive element is provided between each of the input terminals and output terminals. Each resistive elements includes a plurality of resistors connected in parallel, and a plurality of second switches each of which is connected with a corresponding one of the resistors. An equivalent resistance value of the resistive element is obtained between the input terminal and the output terminal by controlling the on/off states of the second switches through the modulating signals to determine which resistors can be selectively connected with the input terminal and the output terminal.
