Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...
How Stable is your Op Amp or FDA design? One of the most important aspects of any end system design is to understand and improve (if necessary) the nominal phase margin for each stage. Since the early ...
The first installment of this article series discussed the need to verify SPICE model accuracy and how to measure the open- and closed-loop small-signal AC output impedance of operational amplifier ...
