Abstract
A programmable current mirror, including a reference system configured to receive a reference current, and a mirror system operatively connected to the reference system and configured to produce an output current based on the applied reference current. The relationship between the reference current and the mirror current is defined by a programmably variable mirroring parameter. The reference system includes a plurality of transistor groups, each transistor group being configured to alter the mirroring parameter via programmable variation of a dimensional parameter associated with the transistor group. Variations to the mirroring parameter produced by one of the transistor groups are scaled relative to variations produced by another of the transistor groups. The reference system, mirror system or both may be implemented with a multistage configuration. The current mirror may also be configured to provide inverse linear programmability.
