Electronics ( 1 of 1) operational Amplifier Design - Coursework Example Non-ideal Op Amps might have inputs, at the two pins, having unequal voltages; there may be current flowing out or into the two input pins. The non-ideal characteristics are responsible for circuit loading, introduced noise, and the reduced Gain and input resistance (Rin). Input offset voltage is a small voltage that is applied at the input terminals in order to make the output voltage zero when two inputs’ terminals are grounded. A number of signal inputs can be integrated into the inverting amplifier via connection of individual sources with separate resistors to an Op Amp’s input; this will result into inverted sum of all the inputs. A summing amplifier’s input combinations produce an output that reflect weighted sum of the total inputs. Figure 1 shows a summing amplifier, a modification of an inverting amplifier; the inverting amplifier has been utilized since it can handle several or many inputs simultaneously.
