Voltage gain is 0 [dB].
This circuit controls output voltage (Vout) equal input
voltage (Vin), and keeps Vout with stable because of high
input impedance and low output impedance.
Vout is shown next formula.
Vout=Vin
For inverting amplifier, Vin is amplified by voltage gain
decided R1 and R2, and phase reversed voltage is
outputted.
Vout is shown next formula.
Vout=-(R2/R1)・Vin
Input impedance is R1.
For non-inverting amplifier, Vin is amplified by voltage
gain decided R1 and R2, and phase is same with Vin.
Vout is shown next formula.
Vout=(1+R2/R1)・Vin
This circuit realizes high input impedance because Input
impedance is operational amplifier’s input Impedance.
