Multipath current source switching device

摘要

The invention discloses a multipath current source switching device, comprising a switching control unit, N current paths, and N loads. Each current path is formed by a constant-current source circuit and a switching circuit. One end of a first load is connected to a load power supply, and the other end of the first load is connected to an output end of a constant-current source circuit of a first current path and one end of a second load; one end of an i
