Abstract

A resistance trimming circuit has a resolution of N=X+Y bits. Included is a first circuit with M resistors, where M=2−1, with each of the M resistors having a resistance of R*(2)*i, i being an index having a value ranging from 1 to 2−1. M switches are associated with the M resistors. Each of the M resistors is coupled between a first node and its one of the M switches, and each of the M switches couples its one of the M resistors to a second node. Included is a second circuit with P resistors, where P=2−1, with each of the P resistors having a resistance of R*i. P switches are associated with the P resistors. Each of the P resistors is coupled between the second node and its one of the P switches, and each of the P switches selectively couples its one of the P resistors to a third node.
