Abstract
A new current measurement setup is presented, which based on randomly orientated NV ensembles in diamonds with a diameter of 150μm. Diamonds are applied directly on a printed circuit board (PCB) track which is used as a Bias-Tee to combine DC current and microwave (MW) excitation. By scanning the MW frequency, characteristic dips in fluorescence intensity are used to deduce DC current and temperature in a measurement range of 2A to 8A and 300K to 380K.
