This book aims to design CMOS programmable current mode building blocks and field programmable analog arrays (FPAAs). A detailed study of programmable current operational trans-conductance amplifiers (OTA) is presented. Five proposed fully differential digitally programmable OTAs based on using fully differential CCs and current division networks are presented. Two of the proposed OTAs are realized using CMOS current division networks while the other three OTAs are realized using MOS current division networks. The proposed OTAs CMOS designs and simulations are presented in details. All the...
