Apa Itu transconductance (Transkonduktansi)?<\/h2>\n

Transkonduktansi<\/strong> adalah ukuran performa dari sebuah transistor bipolar<\/a> atau transistor efek medan (FET)<\/a>. Secara umum, semakin besar nilai transkonduktansi suatu perangkat, semakin besar pula gain (penguatan) yang dapat dihasilkannya, dengan asumsi semua faktor lainnya tetap konstan.<\/p>\n

Secara formal, untuk perangkat bipolar, transkonduktansi didefinisikan sebagai rasio perubahan arus kolektor terhadap perubahan tegangan basis dalam selang waktu yang sangat kecil pada kurva arus kolektor terhadap tegangan basis. Untuk FET, transkonduktansi adalah rasio perubahan arus drain terhadap perubahan tegangan gate dalam selang waktu yang sangat kecil pada kurva arus drain terhadap tegangan gate.<\/p>\n

Simbol transkonduktansi adalah g<\/em>m<\/sub>. Satuan yang digunakan adalah siemens<\/strong>, yaitu satuan yang sama dengan yang digunakan untuk konduktansi<\/a> arus searah (DC).<\/p>\n

Rumus Transkonduktansi<\/h3>\n

Jika dI<\/em> mewakili perubahan arus kolektor atau drain yang disebabkan oleh perubahan kecil dalam tegangan basis atau gate dE<\/em>, maka transkonduktansi dapat dinyatakan dengan rumus:<\/p>\n

g<\/em>m<\/sub> = dI<\/em> \/ dE<\/em><\/p>\n

Ketika selang perubahan tegangan basis atau gate semakin kecil mendekati nol, nilai dI<\/em> \/ dE<\/em> mendekati kemiringan garis singgung pada kurva di titik tertentu. Kemiringan garis ini menunjukkan transkonduktansi teoritis transistor bipolar untuk tegangan basis dan arus kolektor tertentu, atau transkonduktansi teoritis FET untuk tegangan gate dan arus drain tertentu.<\/p>\n","protected":false},"excerpt":{"rendered":"
