    Abstract

    ![CDATA[A digital-to-transcoductance converter is presented for use with digitally programmable Nauta structure operational amplifiers. The converter architecture consists of parallel connected tri-state CMOS inverters sized in such a way as to present a complete range of transconductance tunability at the expense of linearity and transconductance output range. Our converter architecture is analysed under mismatch conditions and shows that our converter meets these design constraints which are required for the programmability of high gain states within digital Nauta op-amps.]]
