A transistor realization of the generalized impedance converter

A transistor realization of a generalized impedance converter (g.i.c.) is developed from an ideal nullor representation. The use of g.i.c.s for realizing low-sensitivity RC-active filters is well established and this new circuit overcomes the requirement for using two operational amplifiers in order to realize a g.i.c. The proposed transistor realization is a single-loop structure with the practical advantage of low output impedance; the use of this circuit in the realization of typical elliptic transfer functions is considered.
