Zusammenfassung: | An example dynamic element matching (DEM) circuit includes: a plurality of bipolar junction transistors (BJTs), each of the plurality of BJTs having a base terminal and a collector terminal coupled to electrical ground; a plurality of pairs of force switches, each pair of force switches coupled to an emitter of a respective one of the plurality of BJTs; a plurality of pairs of sense switches, where each pair of sense switches is coupled to the emitter of a respective one of the plurality of BJTs, a first switch in each pair of sense switches is coupled to a first node, and a second switch in each pair of sense switches is coupled to a second node; a first current source coupled to a first switch in each pair of force switches; and a second current source coupled to a second switch in each pair of force switches. |
