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...
