Compare the two circuits below in terms of gain and phase As

Compare the two circuits below in terms of gain and phase. Assume the input, V_s, is 1 volt (V_s = 1). What type of operational amplifier configuration (non-inverting, inverting, comparator, etc.) is indicated in the following LabView VI?

Solution

9 Ans)

In first op-amp Vout=-R2/R1 * Vs

Gain=Vout/Vs=-R2/R1=-10/10=-1

so Magnitude of gain is 1 and phase is 180 deg as it is -1 where as in

--------------------------

Only question per post will be answered please

Second op-Amp

unity gain buffer=Vout=Vs so gain = and phase =0 deg
