Current-feedback operational amplifiers are devices where the main feedback path from output to input carries a current, and not a voltage, as in voltage feedback op-amps. Current-feedback op-amps do ...

They were museum pieces by the early 1990s: a motorized roll of graph paper across which a pen would traverse in proportion to the voltage ... amplifier comparing the feedback via a potentiometer ...

This chapter presents the concept of feedback, which means looping back a portion of the output voltage or current of an amplifier to control the system within itself. Different types of feedback and ...

When an amplifier is connected in negative feedback a fraction of the output voltage is returned back to the input with a phase angle of 180 o2. In the case of op-amps if we take a fraction of the ...

If you ever wanted to build your own tube amplifier but you were intimidated by working with high voltages, [Marcel]’s low-voltage tube amp design might spark your interest. The design operates ...
