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 ...
Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...
Texas Instruments' Burr-Brown Division recently released the single OPA1641, dual OPA1642, and quad OPA1644 operational amplifiers, which feature a JFET input stage. The parts operate with ±2.25 to ...
