Abstract
An amplifier receives an input and a feedback. A first transistor controlled by the amplifier output is coupled between a supply node and the feedback. A second transistor controlled by the amplifier output is coupled to the supply node and generates a bias current. A trimmed resistor coupled between the feedback and ground includes, for trimming resolution of N-bits, where X+Y=N: M resistors, where M=2−1, each having a resistance equal to R*(2)*i, i being an index having a value ranging from 1 to 2−1, a first of the M resistors having a resistance of R*2, a last of the M resistors having a resistance of R*2*(2−1); and M switches associated with the M resistors. Each of the M resistors is between a first node and its associated one of the M switches. Each of the M switches couples its associated one of the M resistors to a second node.
