Operational amplifiers (commonly called op amps) are a ubiquitous building block for designing electronic circuits. Today, these devices are fabricated as small integrated circuits, but the concept ...
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 preparation for SPICE simulation. The availability of hierarchical blocks for ...
Most ICs’ data sheets list a maximum supplycurrent, but manufacturers often overlookthe measurement conditions. For some rail-to-rail-output op amps, certain operatingconditions can result in supply ...
