Abstract
In this paper a novel transconductance Bi-CMOS stage is described. This design is based on a combined translinear current gain cell and a negative resistance cell, to generate a linear tuneable transconductor. The transconductance stage was designed specifically for an integrated Gm-C filter RF application, and is shown to perform well particularly at high frequencies.
