摘要：In this.paper, we have inves.igated the des.gn parameters.of RF CMOs.cells.which will be us.d for s.itch in the wireles. telecommunication s.s.ems. This.RF s.itch is.capable to s.lect the data s.reams.from the two antennas.for both the trans.itting and receiving proces.es. The res.lts.for the development of a cell-library which includes.the bas.cs.of the circuit elements.required for the radio frequency s.b-s.s.ems.of the integrated circuits.s.ch as.V-I characteris.ics.at low-voltages. contact res.s.ance which is.pres.nt in the s.itches.and the potential barrier with contacts.available in devices.has.been dis.us.ed.
