Bhattacharyya,Dept. of E&ECEWhat is RF? Why Lumped parameters models failed .. Kirchoff's to Maxwell Failure of two port circuit parameter (Z, Y,ABCD) .. Scattering parameter( S-parameter) on the basis of Maxwell equation comes in ..Dr. T. K. Bhattacharyya,Dept. of E&ECEA pplication area of the RF-IC designer Wireless communication Radar Navigation Remote sensing RF identification Automobile and Highways Sensors: Medical Radio- astronomy and space explorationDr. T. K. Bhattacharyya,Dept. of E&ECEB eauty of RF- IC Design : Link between Microwave Engineer and Design Engineerkirchoff s lawTotal voltage around a loop is zero( KVL)No net current build up at any node(KCL) If & =0, (c ) infinitely fast wave propagation of wave gives KVL and KCL As the physical dimension of circuit element & sub- circuit in a IC chip is very less (even less than 1/10thof [ 30 cm in air at 1 GHz] ) , so finiteness of the speed of lightis not noticeableinside chip, so a full transmission line ( Microwave) for on-chip designand Analysis is generally s law is well suited for on-chip Design But for interfacing the RF signals in / out of the chip, we need connectors, boards, cables etc.
