FET Constant Current Sources in Circuits

FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

Evaluating Oxide Reliability With V-Ramp and J-Ramp Testing

The JEDEC 35 Standard (EIA/JESD35, Procedure for Wafer-Level Testing of Thin Dielectrics) describes voltage ramp (V-ramp) and current ramp (J-ramp) tests to monitor oxide integrity. These tests are ...
