The device shown is an npn device which consists of a p . Active Region In this region, collector junction is Reverse Biased and emitter junction is forward biased. 5. The Saturation Region of a FET transistor is the region where the drain current, ID, flowing from the drain to the source of the FET transistor, is the highest for the gate-source voltage, VGS, that is supplied.. The base to emitter junction remains in forward biased condition whereas the collector to emitter junction remains in the reverse biased condition. This region lies between saturation and cutoff. None of the above. Which of the following is not a valid form of.. c) Active region. A transistor works in active region when worked as an Amplifier. In this region, both junctions of the transistor are reverse biased. Question. False. + VCB . b) Resistance. To understand the operation of the BJT as an amplifier or a switching circuit, we will discuss the simplified version of the device shown in Figure 10.2. Vgs>Vth is just an approximation of not being cutoff region. ) cutoff region B) saturation region D) active region 11) The maximum current in a JFET is defined as Ipss and occurs when Vos is equal to A) pinch-off voltage B) a small positive voltage a voltage greater than the pinch-off voltage D) zero Volts 12) For an n-channel JFET IDSS=8 mA and Vp=-6 Volts. Cut off region - A MOS device is said to be operating when the gate-to-source voltage is less than Vth. 1. The linear (active) section of any transistor is useful as an amplifier. A. Cut off, Active and saturation regions of a transistor: Transistor Biasing:-The application of suitable dc voltages across the transistor terminals is called biasing. The transfer characteristics of a base biased transistor has the operation regions, namely, cutoff, active region and saturation region. But in saturation region both junctions are forward biased. This region is known as the active region of a transistor. However, naming it as saturation region may be misunderstood as the saturation region of BJT. The final region of operation of the BJT is the "forward active" region. Consequently, the transistor will function normally in this region. (A) active region. No current flow 2. saturation region: B-E and C-B junctions are forward biased Ic reaches a maximum which is independent of IB . Active region TRANSISTOR AS A SWITCH : ( CUTOFF & Saturation Region) The transistor can be used as a switch by operating it in cut off and the saturation region. In the active region, collector-base junction remains reverse biased while base-emitter junction remains forward biased. Forward Active Region. A) minimum, left of the VCEsat line . If the voltage increases so that forward biases the base-emitter junction the transistor will turn on and vi VBE iBE B B vV I R − = (1.6) Once the transistor is on we still do not know if it is operating in the active region or in the saturation region. Is represented by linear or active region: B-E and C-B junctions are reverse biased while base-emitter of.
