A Low Noise Signal Read-Out Circuit for Integrated Quantum Diamond Magnetometers
Abstract: A customized low-noise signal read-out circuit, which is designed for the implementation of the integrated low power consumption quantum magnetometers based on nitrogen-vacancy centers in diamond, is reported in this article. As the circuit has a 3.7 pA/Hz1/2 low-input noise which is superior to the latest studies, the integrated quantum diamond magnetometer can achieve […]
