Analog Mixed-Signal Design in FinFET Processes

While industry pundits have forecasted the end of analog design in the next leading edge process, the reality is that the practice is still going strong, and there’s no end in sight. Not only are teams still designing data converters, PLLs, filters, and other analog goodies in the latest processes (including FinFET), but design teams

HMI+PLC with extensive analog capability from IDEC

IDEC announces a new model in its FT1A Touch micro programmable controller series of combo HMI+PLC units, the FT1A Touch 14 I/O. New features make the FT1A Touch 14 I/O suitable for advanced analog monitoring and control, allowing users to economically perform both operator interface and control for a much wider range of applications. Many
