Draw the electronic circuit of a subtraction amplifier with two inputs (V. and V2) and one output (V.) implemented using only one operational amplifier. Substitute the equation that gives V. in terms of Vi and V2 using circuit analysis techniques. DO NOT use any pre-driven formula and consider the amplifier is an ideal one.

Expert Solution
Step 1

Draw the electronics circuit of the subtraction amplifier or differential amplifier, with two inputs and one output and using one op-amp.

Electrical Engineering homework question answer, step 1, image 1

Step 2

As the op-amp is ideal, no current flows through it.

Write the expression for voltage V.
