    CMOS MEMS for superhet receiver

    HI, Thanks for the concern in replying to this thread. CMOS MEMS means having both RF MEMS (switches, Phase shifters etc..) and the CMOS on the same IC. generally in a communication RX the amplifying and other circuits are used in IC and the corresponding mechanical systems are used in another...

    MEMS Technology for research

    Hi, If you are a mechanical engineer you can workout with basic cantilever beams. If you wish to use them in biosensors then, you can go through the literature where a lot of materials and shapes of the beams are available and upon inspiration you can propose your own. If you are interested in...
