Use a Comparator or Op-Amp to Simplify Light Dependent Resistor Output

If your project calls for light sensitivity, it’s hard to beat light dependent resistors (LDRs), also known as photoresistors. They’re available for a few cents each, and their resistance varies based on how much light they receive. In the dark, these devices produce resistances in...

How to make precision measurements on a nanopower budget

Gen Vansteeg @ ti.com discuss about precision measurement for nanopower scale using OPAMPs. Heightened accuracy and speed in an operational amplifier (op amp) has a direct relationship with the magnitude of its power consumption. Decreasing the current consumption decreases the gain...
