P 6.5-6 The voltage divider shown in Figure P 6.5-6 has a gain of

Design an operational amplifier circuit to implement the – 10-kΩ resistor.

Figure P 6.5-6

A negative resistor can be constructed from

The voltage output is given by

From Ohm’s law

So if we need R = -10 kΩ, we can simplify if , then

So let’s use our circuit now looks like

This provides the effective negative resistance needed.
