Analog Circuits
Engineers at Massachusetts Institute of Technology (MIT) have devised new analog circuits that will not drain power or create bottlenecks like previous models. The new class of analog circuits eliminates operational amplifiers while maintaining virtually all benefits of operational-amplifier-based circuits. The MIT circuits feature...
