What is the basic idea behind the negative impedance converter? How is
Negative impedance converter (NIC) circuits violate Foster's Reactance Theorem [1] because those circuits provide the negative values of resistance, capacitance and inductance. Thus, NIC circuits are also known as non-Foster circuits.

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.
Reinventing Negative Impedance Converter (NIC)
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.
Electronic How to analyze an opamp based negative impedance
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.

What is the use of the true negative impedance? What is the difference and what is the common between the true and differential negative resistance? You will find answers to all these questions in this exciting circuit story about the mystic phenomenon. The true negative resistance is closely related to the differential negative resistance.

What is the basic idea behind the negative impedance converter? How is
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)..

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.
Reinventing Negative Impedance Converter (NIC)
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.

The negative impedance converter ( NIC) is an active circuit 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.
What is the basic idea behind the negative impedance converter? How is
A generic NIC, shown at right, is a negative impedance converter. Looking into V in, the NIC appears to have an impedance -Z to ground. In other words, the circuit inverts it internal impedance Z to -Z.: Construct the circuit below. Use matched, 1%, precision resistors.To match resistors, start with ten to twenty of each value.

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.
Can we present the negative impedance converter (NIC) as a balanced bridge?
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.
