    摘要: Aspects of the present disclosure relate to a current multiplier that can generate an output current with high linearity and/or high temperature compensation. Such current multipliers can be implemented by complementary metal oxide semiconductor (CMOS) circuit elements. In one embodiment, the current multiplier can include a current divider and a core current multiplier. The current divider can generate a divided current by dividing an input current by an adjustable division ratio. The division ratio can be adjusted, for example, based on a comparison of the input current with a reference current. The core current multiplier can generate the output current based on multiplying the divided current and a different current. According to certain embodiments, the output current can be maintained within a predetermined range as the input current to the current divider varies within a relatively wide range.
