A negative impedance converter (NIC) is a clever circuit, the analysis of which is a favorite exercise set by engineering lecturers everywhere. It's not often used in practice, but it's well worth having in your design kit-bag. I'll show you two real-life applications once we get through the analysis—which is not as hard as it might seem.

Abstract: The authors describe the negative impedance converter, a simple analog building block which can be readily implemented in CMOS. They present a circuit based on the inverse-function approach, providing precise temperature-compensated linear operation.
An Introduction to Negative Impedance Converters
Negative-Impedance Converters The NIC shown in Figure 1 uses an op-amp and resistors to produce an input impedance of Z in = -Z. Design and build a NIC with Z in = -10kΩ. Choose the resistors R to keep the op-amp supply current from exceeding its maximum for the rated range of input voltages.
Electronic How to analyze an opamp based negative impedance
This paper is devoted to the device properties of the negative-impedance converter (NIC), the derivation of potential NIC circuits and their compensation in order to achieve an exact NIC. The behavior of the NIC as a function of frequency and means of extending its useful frequency range are presented. Attention is also devoted to the sensitivity of the NIC to variations in active and passive.

The negative impedance converter (NIC) is a one-port op-amp circuit acting as a negative load which injects energy into circuits in contrast to an ordinary load that consumes energy from them. This is achieved by adding or subtracting excessive varying voltage in series to the voltage drop across an equivalent positive impedance.
Negative Impedance Converter Circuit Cellar
The negative impedance converter (NIC) is an op-amp circuit which acts as a negative load. This is achieved by introducing a phase shift of 180° (inversion) between the voltage and the current for a signal source. There are two versions of this circuit - with voltage inversion (VNIC) and with current inversion (INIC)..
2.4 Unit cell of our negative impedance converter LC transmission line
Negative impedance converter refers to a two-port network whose electrical characteristics when looked from outside presents as a negative impedance (Fig. 1), as the meanwhile according to the type of input control signal, it can be divided into voltage-controlled impedance converter and current- controlled impedance converter.

The Negative Resistance Converter The consequences of a device that could have this property are puzzling. All ordinary devices have some internal resistance inherent to their construction that automatically dissipates energy when a current is flowing.
Negative impedance converter built by operational amplifier according
Current Circuit: Negative Impedance Converter The circuit on the left converts a positive impedance to a negative impedance. So, for example, instead of Ohm's Law (E=IR) it causes a resistor to obey E=-IR. The circuit on the right shows a positive impedance (a 150 ohm resistor) for comparison.
