If the MOSFET is operating in saturation, then the following conditions are satisfied: ( DSAT ) (DS ) P D GS T DSAT DS GS T V V L K W I V V V V V V = + l - = < > 1 2 2 + VDS-+ VGS-ID The design procedure starts finding the main parameters of the technology used, specially K P, VT and lambda.Coming to saturation region, as V DS > V GS – V TH, the channel pinches off i.e., it broadens resulting in a constant Drain Current. Switching in Electronics. Semiconductor switching in electronic circuit is one of the important aspects. A semiconductor device like a BJT or a MOSFET are generally operated as switches i.e., they are either in ...Simplifying a bit, they are: Cutoff (Vgs < Vt) -- No current flows from drain to source. Linear (Vgs > Vt and Vds < Vgs - Vt) -- Current flows from drain to source. The amount of current is roughly proportional to both Vgs and Vds. The MOSFET acts like a voltage-controlled resistor. This region is used for switching.... saturation condition – the NMOS enters the saturation region or the saturation mode. ... Saturation (region - B ) and pMOS transistor switches from Saturation …

In that operation region, a small change in the input voltage results in a large output variation. All these observations translate into the VTC of Figure 5.5. Before going into the analytical details of the operation of the CMOS ...EE 230 PMOS – 19 PMOS example – + v GS + – v DS i D V DD R D With NMOS transistor, we saw that if the gate is tied to the drain (or more generally, whenever the gate voltage and the drain voltage are the same), the NMOS must be operating in saturation. The same is true for PMOSs. In the circuit at right, v DS = v GS, and so v DS < v DS ... I think the part of the discussion you are missing is that for a generic, four-terminal MOSFET it is possible for the source and drain to be swapped depending on the applied voltage. For an NMOS transistor, the source is by definition the terminal at the lower voltage so current always flows from drain to source. For a PMOS transistor, the source …Along with having a high input impedance, MOSFETs have an extremely low drain-to-source resistance (Rds). Because of the low Rds, MOSFETs also have low drain-to-source saturation voltages (Vds) that allow the devices to function as switches. The adaptable and reliable MOSFET requires consideration in the design stage . Types of MOSFET Operating ...

PMOS devices •In steady-state, only one device is on (no static power consumption) •Vin=1: NMOS on, PMOS off –Vout= V OL = 0 •Vin=0: PMOS on, NMOS off –Vout= V OH = Vdd •Ideal V OL and V OH! •Ratioless logic: output is independent of transistor sizes in steady-state Vin Vout Vdd Gndsaturation region is not quite correct. The end point of the channel actually moves toward the source as V D increases, increasing I D. Therefore, the current in the saturation region is a weak function of the drain voltage.
