UB-THRHOD RGION OF OPRTION PRFORMNC CHRCTRITIC OF PD PRCIION MTCHD PIR MOFT FMIY (cont.) ZRO TMPRTUR COFFICINT (ZTC) OPRTION ow voltag systms, namly thos oprating at 5V,.V or lss, typically rquir MOFTs that hav thrshold voltag of V or lss. Th thrshold, or turn-on, voltag of th MOFT is a voltag low which th MOFT conduction channl rapidly turns off. For analog dsigns, this thrshold voltag dirctly affcts th oprating signal voltag rang and th oprating ias currnt lvls. t or low thrshold voltag, an PD MOFT xhiits a turnoff charactristic in an oprating rgion calld th suthrshold rgion. This is whn th PD MOFT conduction channl rapidly turns off as a function of dcrasing applid gat voltag. Th conduction channl inducd y th gat voltag on th gat lctrod dcrass xponntially and causs th drain currnt to dcras xponntially. Howvr, th conduction channl dos not shut off aruptly with dcrasing gat voltag, ut dcrass at a fixd rat of approximatly 6mV pr dcad of drain currnt dcras. Thus if th thrshold voltag is +.V, for xampl, th drain currnt is u at V G = +.V. t V G = +.9V, th drain currnt would dcras to.u. xtrapolating from this, th drain currnt is.u (n) at V G = -.V, n at V G = -.4V, and so forth. This suthrshold charactristic xtnds all th way down to currnt lvls low n and is limitd y othr currnts such as junction lakag currnts. t a drain currnt to dclard zro currnt y th usr, th Vgs voltag at that zro currnt can now stimatd. Not that using th aov xampl, with V G(th) = +.V, th drain currnt still hovrs around n whn th gat is at zro volt, or ground. OW POWR ND NNOPOWR Whn supply voltags dcras, th powr consumption of a givn load rsistor dcrass as th squar of th supply voltag. o on of th nfits in rducing supply voltag is to rduc powr consumption. Whil dcrasing powr supply voltags and powr consumption go hand-in-hand with dcrasing usful C andwidth and at th sam tim incrass nois ffcts in th circuit, a circuit dsignr can mak th ncssary tradoffs and adjustmnts in any givn circuit dsign and ias th circuit accordingly. With PD MOFTs, a circuit that prforms a spcific function can dsignd so that powr consumption can minimizd. In som cass, ths circuits oprat in low powr mod whr th powr consumd is masur in micro-watts. In othr cass, powr dissipation can rducd to nano-watt rgion and still provid a usful and controlld circuit function opration. For an PD MOFT in this product family, thr xist oprating points whr th various factors that caus th currnt to incras as a function of tmpratur alanc out thos that caus th currnt to dcras, thry cancling ach othr, and rsulting in nt tmpratur cofficint of nar zro. On of this tmpratur stal oprating point is otaind y a ZTC voltag ias condition, which is.55v aov a thrshold voltag whn V G = V D, rsulting in a tmpratur stal currnt lvl of aout 68u. For othr ZTC oprating points, s ZTC charactristics. PRFORMNC CHRCTRITIC Prformanc charactristics of th PD MOFT product family ar shown in th following graphs. In gnral, th thrshold voltag shift for ach mmr of th product family causs othr affctd lctrical charactristics to shift with an quivalnt linar shift in V G(th) ias voltag. This linar shift in V G causs th suthrshold I-V curvs to shift linarly as wll. ccordingly, th suthrshold oprating currnt can dtrmind y calculating th gat voltag drop rlativ from its thrshold voltag, V G(th). RD(ON) T VG=GROUND vral of th PD MOFTs produc a fixd rsistanc whn thir gat is groundd. For D8, th drain currnt at V D =.V is at u at V G =.V. Thus just y grounding th gat of th D8, a rsistor with R D(ON) = ~KOhm is producd. Whn an D484 gat is groundd, th drain currnt I D = 8.5 u@ V D =.V, producing R D(ON) = 5.4KOhm. imilarly, D48 and D485 producs 77u and 85u, rspctivly, at V G =.V, producing R D(ON) valus of.kohm and 54Ohm, rspctivly. MTCHING CHRCTRITIC ky nfit of using matchd-pair PD MOFT is to maintain tmpratur tracking. In gnral, for PD MOFT matchd pair dvics, on dvic of th matchd pair has gat lakag currnts, junction tmpratur ffcts, and drain currnt tmpratur cofficint as a function of ias voltag that cancl out similar ffcts of th othr dvic, rsulting in a tmpratur stal circuit. s mntiond arlir, this tmpratur staility can furthr nhancd y iasing th matchd-pairs at Zro Tmpco (ZTC) point, vn though that could rquir spcial circuit configuration and powr consumption dsign considration.
