This makes for a good buffer amplifier, with infinite impedance on the input and zero impedance on the output. Ideally, at least. Figure 3 The buffer amplifier provides infinite input impedance and ...

Input buffer topologies As previously discussed, the transient loading from the sampling circuits generally causes the amplifier to operate in a nonlinear mode and exhibit ringing and/or oscillation ...

5. Power-supply rail with a 1-µF cap connected from V CC to GND.. Amplifier Circuit. The common emitter amplifier and emitter follower will be demonstrated using the same amplifier circuit.

Also, the composite buffer in Figure 2 completely eliminates power-dissipation-related errors in the op-amp input.1 C9 and C10 can be replaced by adjustable shunt regulators and R3 and R4 by ...

Texas Instruments (TI) has introduced a high-input-impedance (Hi-Z) buffer amplifier, capable of supporting frequency bandwidths as high as 3 GHz. The wider bandwidth and high slew rates of the BUF802 ...
