What is the Cutoff Region of a FET Transistor

WebThe output characteristics of the MOSFET contain a cutoff region, a constant current region, and a variable resistance region. When the MOSFET works in the switching state, the MOSFET switches back and forth between the cutoff zone and the variable resistance zone as V GS is turned on/off. WebThus, it can be concluded that MOSFETs can be made to function as electronic switches when made to operate between cut-off and saturation operating regions. Similar to the case of n-channel enhancement type MOSFET, even n-channel depletion type MOSFETs can be used to perform switching action as shown by Figure 2. WebJika ingin membuat MOSFET sebagai saklar, maka kita hanya harus mengkonfigurasinya dalam kondisi saturasi (ON) dan cut-off (OFF). 4. Sebagai Pencampur.

WebPerlu diketahui bahwa mosfet juga memiliki sifat-sifat kelistrikan yang sama yang dialami transistor bipolar , yaitu sifat jenuh dan cut off ( Secara Otomatis ). Mosfet jenuh : bila ID maksimum dan UDS ⤳ nol; Mosfet Cut off : bila UDS maksimum dan ID ⤳ nol. Kedua sifat tersebut dalam mosfet dikendalikan oleh tegangan UGS. WebThe region between cut off and saturation is known as active region. In the active region, collector-base junction remains reverse biased while base-emitter junction remains forward biased. Consequently, the transistor will function normally in this region. Note. We provide biasing to the transistor to ensure that it operates in the active region.
