Its important parameters are also mostly about the turning characteristics or we can understand that the comparator is a transitional circuit form characterized by an analog circuit and featuring digital signal input and output. Negative Feedback Loop (G=Rf/Rin). The op-amp can be considered to be a voltage amplifying device that is designed to be used with external feedback components such as resistors and capacitors between its output and input terminals. When the inverting-phase voltage is 0.1V, and the partial voltage on the 1K resistor is 0.1V, the voltage division on the 100K resistor will be 10V, so the output voltage of Vo is the sum of the partial voltages of 100K and 1K resistors, that is 10.1V. So the current will flow through the 1000K resistor, then the voltage on the 1000K resistor is 10V, because the potential output is lower than the GND, so the output is -10V. There is no basic offset voltage is present in the ideal op-amp.  867. Same as like before, we use two external resistors to create feedback circuit and make a closed loop circuit across the amplifier. Operational Amplifier characteristics.
