[amp_mcq option1=”Vgs > Vds” option2=”Vds > Vgs” option3=”Vds > (Vgs – Vth)” option4=”Vgs > (Vds – Vth)” correct=”option2″]<\/p>\n
The correct answer is: B. Vds > Vgs<\/strong><\/p>\n The channel pinches off when the drain-to-source voltage (Vds) exceeds the gate-to-source voltage (Vgs). This is because the drain-to-source voltage creates an electric field that opposes the flow of current through the channel. When the drain-to-source voltage is high enough, the electric field is strong enough to completely stop the flow of current, and the channel pinches off.<\/p>\n Option A is incorrect because the gate-to-source voltage must be greater than the threshold voltage (Vth) in order to turn on the transistor. However, once the transistor is turned on, the gate-to-source voltage does not affect the channel pinch-off.<\/p>\n Option C is incorrect because the drain-to-source voltage must be greater than the gate-to-source voltage in order to pinch off the channel.<\/p>\n Option D is incorrect because the gate-to-source voltage must be greater than the threshold voltage (Vth) in order to turn on the transistor. However, once the transistor is turned on, the gate-to-source voltage does not affect the channel pinch-off.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Vgs > Vds” option2=”Vds > Vgs” option3=”Vds > (Vgs – Vth)” option4=”Vgs > (Vds – Vth)” correct=”option2″]<\/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-19798","post","type-post","status-publish","format-standard","hentry","category-vlsi-design-and-testing","no-featured-image-padding"],"yoast_head":"\n
