Recently (5/21/25), I published a Design Idea (DI) describing a bidirectional current mirror using just two transistors and a diode, “A two-way mirror—current mirror that is.” That circuit works well ...

A two-way mirror, also called a one-way mirror, is a pane of glass that acts like a regular mirror on one side while allowing someone to see through from the other side. It’s commonly used in ...

A mirror usually feels like the simplest object in the room until you come across one in a hotel, restroom, or fitting area and feel a twinge of doubt. That reaction isn’t random. Some mirrors are ...

EDN Design Ideas (DI) published a design of mine in May of 2025 for a passive two-way current mirror topology that, in analogy to optical two-way mirrors, can reflect or transmit. That design ...
