Patent number: 10996256Abstract: 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.Type: GrantFiled: July 2, 2020Date of Patent: May 4, 2021Assignee: Texas Instruments IncorporatedInventors: Sudeep Banerji, Dattatreya Baragur Suryanarayana, Vikram Gakhar, Preetam Tadeparthy, Vikas Lakhanpal, Muthusubramanian Venkateswaran, Vishnuvardhan Reddy J
