An optimal way to determine an op amp's input capacitance. Steps involved in making the input-capacitance measurement. 1. With a series resistor at the op-amp input, the input capacitance of the op ...

Native SPICE elements that accurately replicate an op amp’s real-world behavior were nonexistent. A transconductance sourcing current from the rails and transitioning to a resistive state as the ...

A key subsystem in a programmable logic controller is the analog input module, which provides a high-precision front end to measure a wide variety of sensors. In many cases, however, the amplifier ...

Zero-drift amplifiers have the lowest input offset voltage (Vos) and offset voltage drift of any operational amplifier (op amp) topology. Compared to best-in-class precision low-input offset-voltage ...
