Frequency-dependent negative resistor
text:
A frequency-dependent negative resistor (FDNR) is a circuit element that exhibits a purely real negative resistance −1/(ω2kC) that decreases in magnitude at a rate of −40 dB per decade. The element is used in implementation of low-pass active filters modeled from ladder filters. The element is usually implemented from a generalized impedance converter (GIC) or gyrator. The impedance of a FDNR is or when s = jω. The definition and application of frequency-dependent negative resistors is discussed
