Abstract
A resistor network with reduced area and/or improved voltage resolution and methods of designing and operating the same are provided. Generally, the resistor network includes a resistor ladder with a first number (n) of integrated resistors coupled in series between a top and a bottom contact, with one or more contacts coupled between adjacent resistors. A second number of integrated resistors is coupled in parallel between the top and bottom contacts, and a third number of integrated resistors is coupled in series between the second integrated resistors and either the top or the bottom contact. Each of the integrated resistors has a resistance of R, and a voltage developed across each resistor in the resistor ladder is equal to a voltage applied between the top and bottom contacts divided by n. Where the second number is n−1, and the third number is 1, the total number of resistors is 2n.
