A two-way current mirror with two BJTs and one diode that can mirror the more positive input side at its output.

The operation of the circuit revolves around the high-side current mirror comprising Q 1 and Q 2. All the circuit components have one overall function: to make the collector currents equal in Q 1 and ...

However, you’ll often see more devices used to improve the characteristics of the current sink or source. In particular, a common design is a current mirror which copies a current from one ...

the ADL5315 high-side monitor has a mirror ratio of 1:1 over six decades, enabling accurate input-current monitoring from 3 nA Accepting the challenges associated with interfacing an optical-power ...
