dc.description.abstractCJ\IOS programmable gain stages form essential building blocks i11 today's Lclccom­m1wicat.iou sys Le ms. For each specific application, there may lie a myriad of poLcnt.ial solnt.ious: however, not all soluLiom; are equally suited Lo solving all problems. Sornc problems may be directly treated with traditional voltage-mode approaches while ot.lier problems may lie more efficiently tackled via less convcnLiomt! currcut-modc methods. In view of such an expansive landscape, the present. work seeks Lo investi­gate t.wo telecommunication applications and Lhe specific solnt.iuu for each. FirsLly, a LradiLional Programmable Gain Amplifier (PGA) is clcsig11ccl for 11:-:c ui Very J-1.igh-Spccd Digit.al Suli:-:cribcr Loops (VDSL). Wide lm,ndwidLh, low noi:-:c, aml high Ii neariLy arc achicve<l using a fully cliffcrcnt.ial, multi-stage, vo!Lagc-modc amplifier with switched resistive feedback Lo set the gain. The pscuclo-consLaul. signal liaudwidt.h is accomplii-;l1ed using switched nested Miller co111pensat.ion for each gain :-:ctt.ing t.o keep Lhe dosed-loop lianclwidLh relatively constant.. Secondly, a novel Programmable Gain Current Conveyor (CCII) is dcsigucd !or use in a T 1 /El Equa.li:t,er Line Int.er face U 11iL (LIU). Being digitally t.nrn,1.blc, t.bc upcu­loop CCII has high input impedance, low output impedance and consLa.nL handwidt.h 1-H:ross all gain set.Lings. l3ot.h programmable gain sLages have been designed am! fabrica.Lcd in Lhc TSMC CMOS 0.35 ??l'm process. Del.ailed analysis, simulation and rucasurcmeuLs a.re shown wit.hiu Lhis thesis.
