Penguat Operasional (Operasional Amplifier)
As shown in the picture sequence above, the output voltage has the same phase with voltage inputs. The amount of strengthening the non-inverting circuit is determined from a comparison of the value of R1 and R2. Resistors R1 and R2 form a resistive divider network to provide the feedback voltage (VA) are needed to reverse the input.
Show that the gain of the amplifier is:
Output voltage can be calculated using the following formula:
