Wopanga makina aku Belgian amatsegula njira yamagetsi a "single-chip".

Tawonapo kangapo kuti magetsi akukhala "chilichonse chathu." Zamagetsi zam'manja, magalimoto amagetsi, intaneti ya zinthu, kusungirako mphamvu ndi zina zambiri zimabweretsa njira yamagetsi ndi kutembenuka kwamagetsi pamalo oyamba ofunika kwambiri pamagetsi. Ukadaulo wopangira tchipisi ndi zinthu zamkati pogwiritsa ntchito zida monga gallium nitride (GaN). Panthawi imodzimodziyo, palibe amene angatsutse mfundo yakuti mayankho ophatikizika ndi abwino kusiyana ndi osakanikirana onse pokhudzana ndi kugwirizanitsa kwa mayankho komanso kusunga ndalama pakupanga ndi kupanga. Posachedwapa, pamsonkhano wa PCIM 2019, ofufuza ochokera ku Belgian Center Imec momveka bwino anasonyezakuti magetsi amtundu umodzi (ma inverters) ozikidwa pa GaN sizopeka konse za sayansi, koma nkhani ya posachedwapa.

Pogwiritsa ntchito gallium nitride paukadaulo wa silicon pa zowotcha za SOI (silicon pa insulator), akatswiri a Imec adapanga chosinthira cha-chip-half-bridge converter. Ichi ndi chimodzi mwazosankha zitatu zapamwamba zolumikizira ma switch amagetsi (ma transistors) kuti apange ma inverters amagetsi. Kawirikawiri, kuti agwiritse ntchito dera, seti yazinthu zosakanikirana zimatengedwa. Kuti mukwaniritse kuphatikizika kwina, seti ya zinthu imayikidwanso mu phukusi limodzi lofanana, lomwe silisintha kuti dera limasonkhanitsidwa kuchokera kumagulu amtundu uliwonse. A Belgian adatha kubereka pafupifupi zinthu zonse za theka la mlatho pa kristalo imodzi: transistors, capacitors ndi resistors. Yankho lake linapangitsa kuti ziwonjezeke kusinthika kwa magetsi pochepetsa zochitika zingapo za parasitic zomwe nthawi zambiri zimatsagana ndi ma frequency transversion.

M'chitsanzo chomwe chikuwonetsedwa pamsonkhanowo, chipangizo chophatikizika cha GaN-IC chinasintha mphamvu yolowera 48-volt kukhala 1-volt yotulutsa magetsi ndi ma frequency a switching a 1 MHz. Njira yothetsera vutoli ikhoza kuwoneka yokwera mtengo kwambiri, makamaka poganizira kugwiritsa ntchito zofufumitsa za SOI, koma ochita kafukufuku akutsindika kuti kuphatikizika kwapamwamba kwambiri kuposa kuchotsera mtengo. Kupanga ma inverters kuchokera kumagulu ang'onoang'ono kudzakhala okwera mtengo kwambiri potanthauzira.
