Inventor： Sudeep Banerji ,  Dattatreya Baragur Suryanarayana ,  Vikram Gakhar ,  Preetam Tadeparthy ,  Vikas Lakhanpal ,  Muthusubramanian Venkateswaran ,  Vishnuvardhan Reddy J

IPC: H02M3/156 ,  G01R31/01 ,  H02M1/00

Abstract: A current detection system includes an inductor and a detection circuit coupled across the inductor. The inductor is configured to receive an input signal that includes an input current and generate a voltage across the inductor. The current detection circuit includes a sensing network and a transconductance amplifier. The sensing network includes a capacitor and is configured to monitor a voltage across the inductor. The transconductance amplifier is configured to receive a differential voltage indicative of a voltage drop across the capacitor and output a differential output current proportional to the differential voltage.
