Operational Amplifier Fundamentals Unit 4 – The Voltage Follower
NEW TERMS AND WORDS
voltage follower - a circuit in which the output voltage is equal to and in phase with the circuit
input voltage.
unity gain amplifier - an amplifier configured with a gain of 1.
small-signal - output voltages typically less than 1 Vpk-pk.
large-signal - typical output voltages between 10 Vpk-pk and 20 Vpk-pk.
full-power bandwidth - the highest large-signal frequency at which the amplifier delivers rated
output without distortion.
Fractional gain - a gain that is less than unity.
slope - change in voltage divided by change in time.
rated output - the maximum output voltages at which an op amp is designed to operate.
