Hi team,

Can you please explain me how will be the output of this circuit .Here we are giving the VG1=-2v and Providing the negative offset as -1.65V

    Maheswari,

    1. Your circuit is an inverting summing amplifier.  It uses the equation Vout = Vg1*(-R3/R1) + Vg2*(-R3/R2).  In your question you do not identify the value of Vg2.  We can use the equation to calculate the output, but I need to know Vg2.
    2. This document covers the inverting summing amplifier topology:  Inverting Summer Circuit
    3. You can also use TINA SPICE to calculate your DC output by selecting Analysis>DC Analysis>Calculate nodal voltages.  Doing this will display the DC volage on each volt meter.

    Best regards, Art
