Resumen
A binary genetic encoding (BGE) representation for the automatic synthesisof mixed-mode circuit topologies, is introduced. First, the genetic encodingof unity-gain cells (UGCs), such as voltage (VF) and current followers (CF), andvoltage (VM) and current mirrors (CM), is presented. New BGEs for the VM andCM are introduced. Second, the UGC’s chromosomes are combined to synthesizemixed-mode circuit-topologies, namely current conveyors and current-feedback operationalamplifiers (CFOA). Five strategies for the combination or superimposing ofUGCs are introduced. The proposed BGE has been implemented inMATLAB™, andlinks SPICE to evaluate the populations with different integrated circuit technologies. Some new synthesized circuit topologies are shown along with their chromosome description.
