Abstract :
Negative-impedance convertors for lowpass active RC filters must respond down to zero frequency; any attendant drift is unwelcome. A relatively simple circuit is described wherein a balanced input stage feeds an unbalanced output stage, which, in turn, feeds back to both input terminals in the same phase.
