Tailoring the Design of Transimpedance Amplifiers to Infrared Sensor Apps (Part 2)

For Part 1, click here. High-speed optical communications applications have some high-level transimpedance-amplifier (TIA) circuit similarities with laser rangefinders (LRFs) and LiDAR. However, there ...

Universal purpose optoelectronic logic element with input optical switching of AND/NAND, OR/NOR and XOR/XNOR functions

The optoelectronic logic element AND, OR and XOR is considered, the output signal of which can be inverted when the input control signal is applied, thereby converting the logic element into NAND, NOR ...
