The practical broadband buffer circuit is as shown in the figure. This circuit uses the broadband integrated op-amp OPA606. The OPA606 is the MOSFET input type medium isolation operational amplifier. it has the features of wide frequency band, small bias current, low offset voltage and low distortion degree. In this figure, the input signal adds to the in-phase input port (pin-3) of the OPA606, the output port (pin-6) is connected with the inverting input port (pin-2) by the wire, the circuit forms the voltage follower, the circuit of the figure has the bandwidth of more than 12MHz, the input impedance is 1013Ω.
