A circuit or sub-circuit that as accurately as possible preserves the voltage characteristics of a signal while providing additional current. Typically used in situations where a circuit cannot drive the load that is presented to it.

There are several ways to "amplify" a signal, not only its amplitude is important. Buffers essentially amplify "current", or "input power". They typically have a very high input impedance and low inpu …

Per problem description, all indications are that the input impedance of the tested circuit is fairly low, under 100 kOhm or less. Which isn't expected, since the input leakages and offsets for the LP …

Does the filter "require" buffers? "Require" and "operate effectively" are strong words. Theoretically, if the input source has an impedance different from zero, and the next stage has an impedance le …

-inverting buffer, a pair of basic CMOS transistors forms an inverting circuit, so an non-inverting function must be made out of two inverting gates in sequence. …

be far from perfect, because the impedance of output transistors is not a constant during signal switch. A true impedance-controlled (and slew rate controlled) output buffer consists of HUNDREDS of …
