Wanem samting i wok bung namel long HCMOS na LVCMOS?
Long lukluk bilong 'integrated circuit technology evolution' na 'taxonomy', CMOS, HCMOS, na LVCMOS i no gat wanpela 'parallel' o 'substitutional' rilesensip. Tasol, ol i kamapim wanpela 'hierarchical system' we ol i makim long ol narapela narapela 'dimensions' na 'features' we i wankain.
As rilesensip i ken kamap olsem: LVCMOS i no neks-jeneresen bihain long HCMOS, tasol em i wanpela bikpela brens we i stap aninit long "voltage domain". Long sait bilong pefomens, ol LVCMOS divais bilong nau i winim tru ol HCMOS divais bilong bipo. Tupela i bilong ol narapela narapela tingting na tupela i wok bung wantaim long ol nupela teknoloji.
1. As tingting: CMOS Teknoloji
CMOS teknoloji i stap olsem as bilong olgeta narapela kain teknoloji. Bikpela samting bilong en em long yusim ol komplimentari P-MOS na N-MOSFET long wokim ol inveta o ol narapela lojik geit, na dispela i mekim na ol i no yusim wanpela pawa. Olgeta HCMOS na LVCMOS divais we mipela i toktok long en hia i gat dispela bikpela samting.
2. Teknoloji Evolusen Bes long Pefomens Jeneresen (Praimeri Dimensen)
Dispela dimensen i stap long taim na pefomens, na i soim ol wok i kamap long ol wok bilong wokim ol samting.
Tradisenel CMOS (olsem, 4000 Series)
Ol samting: I adoptim ol wok bilong wokim ol samting long stat wantaim bikpela sais bilong ol samting na bikpela 'parasitic capacitance'. Em i gat bikpela 'operating voltage range' (3-15V) tasol em i save kisim hevi long longpela 'propagation delays' (inap long ~100ns), liklik spit, na liklik 'output driving capabiliti'.
HCMOS (High-Speed CMOS)
Ol samting: Taim ol i daunim ol 'transistor dimensions', 'parasitic capacitance' na 'gate capacitance' bilong ol divais i go daun tru. Dispela impruvmen i sotim ol 'propagation delays' tru (inap long ~10ns) na tu i holim liklik 'static power consumption'. Pawa bilong en long draivim autput i kamap gutpela moa.
Akademik Posisen: HCMOS i makim wanpela historik teknoloji node. Em i makim taim we CMOS teknoloji i winim na winim spit bilong bikpela TTL lojik long dispela taim, na i kamapim ol gutpela samting bilong CMOS long pefomens na pawa konsumsen. Tipikel ripresentativ bilong en em 5V-operated 74HC series. Yumi mas luksave olsem HCMOS em i sotpela nem bilong High-Speed CMOS, i no High-Voltage CMOS. Long ol wok, ol i no save yusim dispela tok 'High-Voltage CMOS; sapos i gat nid, ol i mas sotim nem bilong en olsem HVCMOS.
3. Klasifikesen bilong Akiteksa bihainim Saplai Voltej (Narapela Kros-Dimensen)
Dispela dimensen em i standet long saplai voltej na i wankain olsem pefomens-bes dimensen.
5V CMOS
Insait long en i gat ol CMOS bilong bipo na planti HCMOS divais (olsem, 74HC series). Dispela em i namba wan bikpela 'standardized voltage domain'.
Low-Voltage CMOS
Mining: Em i wanpela jenerel tok bilong olgeta CMOS lojik famili wantaim ol opereting voltej we i daunbilo tru long 5V standet. Divelopmen bilong en i kamap long rot bilong 'dynamic power consumption optimaisation', long wanem, 'dynamic power consumption' bilong wanpela 'circuit' i wankain olsem 'square' bilong 'supply voltage'.
Ol sabkategori: LVCMOS i bruk moa long voltej bilong kamapim ol standet:
3.3V (LVCMOS): eksampel, 74LVC series
2.5V, 1.8V, 1.5V, 1.2V, na ol narapela: Taim ol proses node i go het, ol opereting voltej i go daun yet.
Afiliesen na Kontemporeri Integresen
Historical Subordination: Long histori bilong teknoloji divelopmen, HCMOS (olsem, 74HC) em i wanpela pefomens sabklas bilong CMOS teknoloji.
Cross-Dimensional Overlap: HCMOS (emphasising speed) na LVCMOS (emphasising voltage) em ol konsep we i kamap long ol narapela narapela klasifikesen kraeteria. Wanpela 'chip' tasol inap long stap insait long tupela kain wantaim.
Olsem, 74HC em i 5V HCMOS.
74LVC em i 3.3V LVCMOS, na spit bilong en i winim 74HC. Olsem na, 74LVC em i LVCMOS na i inapim tru "high-spid" mak.
Kontemporari Integresen na Terminoloji Evolusen:
Insait long ol 'submicron' na 'deep-submicron' CMOS proses bilong nau, liklik voltej i kamap olsem wanpela samting we ol i mas mekim pastaim long kisim bikpela spit na liklik pawa konsumsen. Olsem na, olgeta nupela CMOS integreted seket i gat "low-voltage" long en.
"High-speed" em i no moa wanpela nem we i stap tasol long ol spesifik prodak tasol em i wanpela samting we i stap long olgeta hap bilong moden CMOS teknoloji. Insait long ol wok bilong skul na enjiniaring, ol i save yusim dispela tok "HCMOS" long makim olgeta 'high-performance CMOS circuits we i kamap long ol nupela proses, na planti bilong ol dispela circuit i stap aninit long kategori bilong LVCMOS.
Long Kontemporeri Konteks:
CMOS: Olsem wanpela ambrela toktok bilong dispela teknoloji, insait long ol 'crystal oscillator' autput signal, em i makim wanpela 'square wave' signal autput.
HCMOS: Long bikpela mining bilong en, em i tok klia long ol gutpela wok bilong ol CMOS seket bilong nau.
LVCMOS: Em i tok klia long 'electrical standard' bilong 'low operating voltage'.
Olsem na, taim ol i stori long wanpela "3.3V, hai-spid CMOS signal", stretpela tok bilong ol saveman em olsem: Dispela signal i bihainim LVCMOS (eg, LVC) lektrikel standet na i soim ol hai-spid mak bilong ol CMOS proses bilong nau. Olsem wanpela bikpela teknoloji, bikpela samting bilong HCMOS-pefomens impruvmen long rot bilong proses skeling-i bin kisim na winim olgeta moden LVCMOS teknoloji. Tupela tingting i bilong ol narapela narapela sait insait long tiori na ol i bin bungim olgeta insait long ol wok bilong mekim.
