Mukupesana neaviri anotenderera crystal triode, inowanzo nzwikwa kuti kugadzira iyoMOSFETmaitiro haashandise kuyerera kwemagetsi, asi kunongoda kuti GS voltage ive yakakwirira kupfuura imwe kukosha. Zviri nyore kuita izvi, isu tinonyanya kuda imwe chiyero.
Kune chimiro cheMOSFET, isu tinogona kuwana muGS, GD, pachave nekumwe parasitic capacitance, uye iyo MOSFET drive, kutaura zvazviri, ndeyekuchaja uye kuburitsa capacitance. Pakuchaja kwema capacitors isu tinongoda ikozvino yakakwana, nekuti iyo capacitor munguva yekuchaja yakaenzana neiyo capacitor sepfupi-circuit, ino nguva yekukurumidza ikozvino ichave yakakwirira kupfuura iyo general mamiriro kukosha. Naizvozvo, isu tinobva tasarudza kana kugadzira MOSFET dhiraivha dhiraivha chirongwa, chinhu chekutanga kutarisisa kune saizi yekukasira pfupi-yedunhu ikozvino inogona kupihwa.
Kechipiri, NMOS, iyo inoshandiswa zvakanyanya kune yakakwira yekupedzisira drive, inofanirwa kurega gedhi remagetsi richipfuura iro sosi voltage painoitisa. Yakakwira-yekupedzisira dhiraivha MOSFET mune-nguva, iyo sosi voltage uye drain voltage saizi yakafanana, saka panguva ino magetsi egedhi anofanira kunge ari 4V kana 10V yakakura kupfuura Vcc. Kana mune imwecheteyo sisitimu, uchida kuwana yakakura kupfuura Vcc gedhi voltage, iwe unofanirwa hunyanzvi mukudzora voltage redunhu. Mazhinji madhiraivha anoumbwa nemapombi ekuchajisa, zvinofanirwa kucherechedzwa kuti isu tinofanirwa kutora yakakodzera yekunze capacitor, kuti tiwane yakakwana yenguva pfupi-yekutenderera ikozvino kutyaira iyo MOSFET.
