Sensor Gap TLP: Expanding Time Resolution and Pulse Duration Beyond Conventional Values of Standard and Very Fast Transmission Line Pulsing

A novel Transmission Line Pulsing (TLP)-based technique, the "sensor gap TLP" (sg-TLP) is introduced. Instead of using dedicated current and/or voltage sensors like established methods, sg-TLP utilizes two voltage sensors, which are deliberately spatially separated. In this way it is possible to extract fast but long voltage and current transients at the DUT. The results of the new approach are compared directly to established TLP methods using a TVS diode and a SiC power MOSFET. The sg-TLP combines a very high temporal precision with the capacity to apply "long" pulses of 100 ns or more in a single measurement setup.
