Proportional<\/strong><\/p>\n<p>The transconductance (gm) of a transistor is the ratio of the change in collector current (\u00ce\u0094Ic) to the change in base-emitter voltage (\u00ce\u0094Vbe). It is a measure of how much current the transistor can amplify.<\/p>\n<p>The transconductance of a transistor is proportional to the input voltage (Vbe). This means that the higher the input voltage, the higher the transconductance.<\/p>\n<p>The transconductance of a transistor is also affected by the temperature. The higher the temperature, the lower the transconductance.<\/p>\n<p>The transconductance of a transistor is an important parameter in the design of amplifiers. It is used to calculate the gain of an amplifier.<\/p>\n<p>The other options are incorrect because:<\/p>\n<ul>\n<li>Option A is incorrect because the transconductance is proportional to the input voltage, not inversely proportional.<\/li>\n<li>Option C is incorrect because the transconductance is not exponentially dependent on the input voltage.<\/li>\n<li>Option D is incorrect because the transconductance is dependent on the input voltage.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Inversely proportional&#8221; option2=&#8221;Proportional&#8221; option3=&#8221;Exponentially dependent&#8221; option4=&#8221;Is not dependent&#8221; correct=&#8221;option2&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[687],"tags":[],"class_list":["post-19884","post","type-post","status-publish","format-standard","hentry","category-vlsi-design-and-testing","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>gm is . . . . . . . . on input voltage Vbe.
