INVESTIGATION OF CIRCUIT IMPLEMENTATIONS OF C-NEGATRONS ON THE BASIS OF NEGATIVE-RESISTANCE CONVERTERS

Abstract

The paper considers four basic circuits of C-negatrons on the basis of negative resistance converters built on operational amplifiers (Op-Amp). It is shown that when positive voltage feedback is used active Cnegatron is realized and in the case of current positive feedback – a passive C-negatron is implemented. Circuits on the basis of U-IC converters have the highest maximal operating frequencies. An advantage of the C-negatron circuits built on Op-Amp is their simplicity, high accuracy, realization of the negative capacitance value, wide operation frequency range.
