New ideal active inductance and frequency-dependant negative resistance using d.v.c.c.s./d.v.c.v.s.: applications in sinusoidal-oscillator realisation

A new grounded-capacitor simulation of driving-point impedances of the form as and bs2, corresponding to ideal inductance and frequency-dependent negative resistance (f.d.n.r.) elements, respectively, is presented. The configurations use the minimum of passive components with the d.v.c.c.s./d.v.c.v.s. as the active element. Applications of the active inductance and f.d.n.r. are then proposed in the realisation of some single-resistor-controlled RC oscillators.
