We are offering resistors network.a resistor ladder is an electrical circuit made of repeating units of resistors. Two configurations are
discussed below, a string resistor ladder and a r-2r ladder.an r-2r ladder is a simple and inexpensive
way to perform digital-to-analog conversion, using repetitive arrangements of precision resistor networks
in a ladder-like configuration. A string resistor ladder implements the non-repetitive reference network.
