Pls does anyone know how to derive for Vout1 and Vout3 in terms of Va and Vb for an inverting operational amplifier. Thank you.
See inverting amplifier section in http://physics.usask.ca/~angie/ep316/lab7/theory.htmSammyboss said:Pls does anyone know how to derive for Vout1 and Vout3 in terms of Va and Vb for an inverting operational amplifier. Thank you.
Thanks a lot. that really helpedyungman said:There is no Va and Vb! I see two input voltage. I only see Vin1 and Vin2. So you look at Vin1 and Vin2 contribute. Vout1 part due to Vin1 is -(R3/R1)Vin1. Vout1 due to Vin2 is -(R3/R2)Vin2 so the total Vout1:
[tex] V_{out1}=-\left[ \frac{R_3}{R_1}V_{in1}+\frac{R_3}{R_2}V_{in2} \right][/tex]
You try to do the next one.
An inverting operational amplifier is a type of electronic circuit that amplifies the input signal while inverting its polarity. It is commonly used in signal processing and amplification applications.
An inverting operational amplifier consists of an input terminal, an output terminal, and a negative feedback loop. The input signal is fed into the negative input terminal, and the output signal is amplified and inverted at the output terminal. The feedback loop adjusts the gain of the amplifier to maintain stability.
The equation for Vout in an inverting operational amplifier is Vout = -Rf/Rin * Vin, where Rf is the feedback resistor and Rin is the input resistor.
To derive the equation for Vout in an inverting operational amplifier, you can use Kirchhoff's current law and Ohm's law to analyze the circuit. By setting the input and output currents equal to each other, you can solve for Vout in terms of Vin, Rf, and Rin.
An inverting operational amplifier is commonly used in audio amplifiers, signal filters, and instrumentation amplifiers. It is also used in feedback control systems and inverting summing circuits.
