Transistors come in different flavors. Tubes used an electric field to regulate current flow, and researchers wanted to find something that worked the same way without the drawbacks like vacuum and ...
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 ...
1. This circuit uses a JFET to bootstrap the cathode of the photodiode. It eliminates the effect of diode resistance and capacitance. This improves bandwidth and reduces noise, but puts a dc voltage ...
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 ...
