Operational amplifiers (op amps) can be used to create (1) precision current sources and sinks, which range from submicroamps to milliamps, and (2) current regulators, which range from milliamps to ...

The op amp — short for operational amplifier ... is very low which means you can draw more current without disturbing the output voltage much. Comparing voltage divider performance with ...

One good text on this topic is application note AN18 by Jim Williams, which demonstrates various ways to increase an op amp’s output current, voltage swing, or both. Speaking about bandwidth ...

It is also called a voltage to current converter or V to I converter. It is called transresistance because the efficiency of the amplifier is measured in units of resistance. The analysis will be done ...

After a brief review of the history of the K2-W vacuum-tube op amp, an LTspice model is used to create its schematic in ...
