在(zai)(zai)本實施例中,定義為vrefp1=vrefn,然(ran)而,可(ke)以(yi)(yi)定義為vrefp1≠vrefn,只(zhi)要(yao)它(ta)們是vpp/2左(zuo)右的(de)電(dian)(dian)壓(ya)即(ji)可(ke)。在(zai)(zai)中間電(dian)(dian)位(wei)(wei)(wei)生成電(dian)(dian)路ivg中,電(dian)(dian)阻(zu)(zu)(zu)元件(jian)(jian)r3和(he)電(dian)(dian)阻(zu)(zu)(zu)元件(jian)(jian)r4串聯耦合在(zai)(zai)高電(dian)(dian)源電(dian)(dian)位(wei)(wei)(wei)(vpp)與地電(dian)(dian)位(wei)(wei)(wei)(gnd)之間,并且(qie)從(cong)電(dian)(dian)阻(zu)(zu)(zu)元件(jian)(jian)r3和(he)電(dian)(dian)阻(zu)(zu)(zu)元件(jian)(jian)r4的(de)連(lian)接節(jie)點得(de)到第(di)二電(dian)(dian)位(wei)(wei)(wei)(vrefp2)。假設電(dian)(dian)阻(zu)(zu)(zu)元件(jian)(jian)r3的(de)電(dian)(dian)阻(zu)(zu)(zu)值為r3且(qie)電(dian)(dian)阻(zu)(zu)(zu)元件(jian)(jian)r4的(de)電(dian)(dian)阻(zu)(zu)(zu)值為r4,則第(di)二電(dian)(dian)位(wei)(wei)(wei)(vrefp2)的(de)值通過以(yi)(yi)下等式(2)給出。

接下來(lai),解(jie)釋操(cao)作。這里,假設“h”為(wei)低電源電位(vdd),“hh”為(wei)高電源電位(vpp),以及(ji)“l”是地(di)電位(gnd)。地(di)電位也稱為(wei)參(can)考電位。
首先,當輸入信號(hao)(hao)(in)為(wei)(wei)(wei)“l”時,節(jie)點(dian)(dian)(dian)n1變為(wei)(wei)(wei)“h”且(qie)nmos晶(jing)(jing)體(ti)管(guan)(guan)mn1截止。同時,柵(zha)極控制(zhi)電(dian)路gc的(de)輸出(chu)(chu)節(jie)點(dian)(dian)(dian)n4為(wei)(wei)(wei)vrefp2+|vtp|;相應地,如(ru)果(guo)(vpp-vrefp2-|vtp|)>|vtp|,則(ze)pmos晶(jing)(jing)體(ti)管(guan)(guan)mp1導通,并且(qie)作為(wei)(wei)(wei)pmos晶(jing)(jing)體(ti)管(guan)(guan)mp1和(he)pmos晶(jing)(jing)體(ti)管(guan)(guan)mp2的(de)連接節(jie)點(dian)(dian)(dian)的(de)節(jie)點(dian)(dian)(dian)n3被上拉至“hh”。如(ru)果(guo)(vpp-vrefp1)>|vtp|,則(ze)pmos晶(jing)(jing)體(ti)管(guan)(guan)mp2也導通,輸出(chu)(chu)信號(hao)(hao)(out)也設置為(wei)(wei)(wei)“hh”,并且(qie)作為(wei)(wei)(wei)nmos晶(jing)(jing)體(ti)管(guan)(guan)mn1和(he)nmos晶(jing)(jing)體(ti)管(guan)(guan)mn2的(de)連接節(jie)點(dian)(dian)(dian)的(de)節(jie)點(dian)(dian)(dian)n2經由nmos晶(jing)(jing)體(ti)管(guan)(guan)mn2被上拉至(vrefn-vtn)且(qie)穩定。
另一方(fang)面,當輸入(ru)信(xin)(xin)號(hao)(in)為“h”時(shi),節(jie)點(dian)(dian)(dian)n1變為“l”,nmos晶體(ti)(ti)(ti)管(guan)mn1導通,并(bing)且(qie)作為nmos晶體(ti)(ti)(ti)管(guan)mn1和(he)nmos晶體(ti)(ti)(ti)管(guan)mn2的(de)連接節(jie)點(dian)(dian)(dian)的(de)節(jie)點(dian)(dian)(dian)n2被(bei)(bei)下(xia)拉(la)至(zhi)(zhi)“l”。如果vrefn>vtn,則nmos晶體(ti)(ti)(ti)管(guan)mn2也(ye)導通,并(bing)且(qie)輸出信(xin)(xin)號(hao)(out)也(ye)被(bei)(bei)設置為“l”。此外(wai),輸出節(jie)點(dian)(dian)(dian)n4為“hh”。因此,pmos晶體(ti)(ti)(ti)管(guan)mp1截(jie)止,并(bing)且(qie)節(jie)點(dian)(dian)(dian)n3經由(you)pmos晶體(ti)(ti)(ti)管(guan)mp2被(bei)(bei)下(xia)拉(la)至(zhi)(zhi)(vrefp1+|vtp|)且(qie)穩定。

根(gen)據這些(xie)器件,變(bian)得不需要制(zhi)造具(ju)有高耐受電壓結構(gou)的pmos晶體管(guan)mp1和(he)mp2以及nmos晶體管(guan)mn1和(he)mn2。因此(ci),可(ke)以緩解制(zhi)造工藝變(bian)得復雜(za)且(qie)生產成本增加(jia)的問題。
然(ran)而,當輸(shu)出信號(out)從“hh”變(bian)為“l”時(shi)(shi),反相(xiang)器inv2的輸(shu)出信號(in2)變(bian)為“h”;相(xiang)應地,vgsn1變(bian)為vgsn1=vdd。節點n2的電(dian)位變(bian)為vdsn1。通(tong)過(guo)vrefn-vdsn1給出vgsn2,并且當vrefn=vpp/2時(shi)(shi)得到(dao)(dao)vgsn2=vpp/2-vdsn1。當作為實際使(shi)用(yong)的示例(li)假設vpp=3.3v且vdd=1.8v時(shi)(shi),通(tong)過(guo)vgsn2=1.65v-vdsn1且vgsn1=1.8v給出vgsn2和vgsn1,并且得到(dao)(dao)vgsn2<vgsn1。因(yin)此,nmos晶(jing)體(ti)管mn2的導通(tong)阻抗(kang)變(bian)得大(da)于nmos晶(jing)體(ti)管mn1的導通(tong)阻抗(kang),并且得到(dao)(dao)vdsn2>vdsn1。因(yin)此,nmos晶(jing)體(ti)管mn2的漏極(ji)-源(yuan)極(ji)電(dian)壓(ya)變(bian)大(da)。通(tong)過(guo)vdsn2=vpp-vdsn1=3.3v-vdsn1=1.8v+1.5v-vdsn1=vdd+1.5v-vdsn1給出vdsn2,并且當vdsn1變(bian)為vdsn1<1.5v時(shi)(shi),得到(dao)(dao)vdsn2>vdd。
當(dang)(dang)輸(shu)出信號(hao)(out)從(cong)“l”變為(wei)(wei)(wei)“hh”時,節點n4處于(yu)vrefp2+|vtp|,并(bing)且(qie)(qie)(qie)得(de)到(dao)(dao)vgsp1=vpp-vrefp2-|vtp|。當(dang)(dang)vrefp2=vpp/2-|vtp|時,得(de)到(dao)(dao)vgsp1=vpp/2。節點n3的電位(wei)變為(wei)(wei)(wei)vpp-vdsp1。通(tong)(tong)過(vpp-vdsp1)-vrefp1給(gei)出vgsp2,并(bing)且(qie)(qie)(qie)當(dang)(dang)vrefp1=vpp/2時得(de)到(dao)(dao)vgsp2=vpp/2-vdsp1。當(dang)(dang)作為(wei)(wei)(wei)實(shi)際使(shi)用的示例假設vpp=3.3v且(qie)(qie)(qie)vdd=1.8v時,通(tong)(tong)過vgsp2=1.65v-vdsp1且(qie)(qie)(qie)vgsp1=1.65v給(gei)出vgsp2和vgsp1,并(bing)且(qie)(qie)(qie)得(de)到(dao)(dao)vdsp1>0v;因(yin)此,得(de)到(dao)(dao)vgsp2<vgsp1。因(yin)此,pmos晶體管mp2的導通(tong)(tong)阻抗變得(de)大于(yu)pmos晶體管mp1的導通(tong)(tong)阻抗,并(bing)且(qie)(qie)(qie)得(de)到(dao)(dao)vdsp2>vdsp1。因(yin)此,pmos晶體管mp2的漏極-源極電壓變大。通(tong)(tong)過vdsp2=vpp-vdsp1=3.3v-vdsp1=1.8v+1.5v-vdsp1=vdd+1.5v-vdsp1給(gei)出vdsp2,并(bing)且(qie)(qie)(qie)當(dang)(dang)vdsp1<1.5v時,得(de)到(dao)(dao)vdsp2>vdd。
一般地,通過以下等式(3)表(biao)示熱載(zai)子(hci)劣化與(yu)vds之間的關系。
即,當vdsn2較大時,nmos晶體管(guan)mn2的熱載子劣化指數(shu)級(ji)增加。具體地,在上(shang)述電(dian)路中,采(cai)用(yong)低耐受電(dian)壓(ya)(ya)晶體管(guan),并且輸出高幅度的電(dian)壓(ya)(ya)。因此,超(chao)過vdd的vds可以如上(shang)文(wen)所述施加,并且劣化變得嚴重。
