#175163 - one doubt Responding to: ???'s previous message |
A buffer is used to transfer a voltage from a first circuit, having a high output impedance level, to a second circuit with a low input impedance level. For my application first circuit is an opamp based differential amplifier which has high input impedance and low output impedance. The second stage is an opamp based butterworth low pass filter which also has high input impedance and low output impedance. Then what would be the role of a buffer here?
