A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

Operational amplifiers (op amps) are almost the perfect amplifier. As long as you keep a few important details in mind, their imperfections will seem invisible. Figure 1. This simple non-inverting op ...

In this lab, Mercer and Miclaus introduce the operational amplifier (op amp) in switch-mode configuration needed to obtain an op amp voltage comparator’s behaviour. The voltage comparator circuit’s ...

An instrumentation amplifier (INA) built using three operational amplifiers (op amps) can provide performance advantages in terms of high input impedance, low output impedance, easily adjustable gain, ...

An operational amplifier or op-amp is simply a linear Integrated Circuit (IC) having multiple-terminals. The op-amp can be considered to be a voltage amplifying device that is designed to be used with ...

A persistent issue with Op-Amps is thermal drift — a phenomenon where the amplifier’s input offset voltage varies over time and with temperature fluctuation. Operational Amplifiers (Op-Amps) are ...

An amplifier is an electronic device that increases the magnitude of a signal, typically a voltage or current. It takes in a weak electrical signal, like a small voltage signal from a microphone; uses ...
