Rail-to-rail op amps preserve dynamic range but have other costs. You can simplify op-amp selection by focusing on prime specification parameters. Ever since pioneering device engineer Bob Widlar in ...

Modeling the performance of an analog device with SPICE is one of the standard techniques used by circuit designers to perform initial characterization and performance analysis before putting together ...

Previous installments of this series discussed the need to verify SPICE model accuracy and how to measure the output impedance and small-signal bandwidth of operational amplifier (op amp) models. In ...
