WebJul 25, 2016 · This modified drain-current expression is a first-order approximation that is reasonably accurate for FETs with channel length greater than, say, 2 µm. As the channel length decreases, so-called “short-channel effects” become more influential, and thus the above expression (which does not account for short-channel effects) becomes less valid.

WebWhen VDS > VDS,sat, the channel is “pinched” off at drain end (hence the name “pinch-off region”) Drain mobile charge goes to zero (region is depleted), the remaining elecric field … Webextend all the way from the source to drain, the channel is said to be pinched off. Once this occurs, the PMOS transistor is no longer in the triode/linear region, but is rather in saturation. Hence, a PMOS transistor is in saturation when it is on (i.e. VSG ≥VTp) and the following relationship holds VSD ≥VSG −VTp (2)

This is a generic prototype and is suitable for any variation on device and bias type. Ultimately, all of the amplifiers can be reduced down to this equivalent, occasionally with some resistance values left out (either opened or shorted). earl fitzwilliam trustWebIn the PMOS device, the drain current has an inverse response to the gate voltage: when \(v_\text{IN}\) rises, \(i_D\) falls. Since the resistor is positioned between the drain and ground, a smaller current means a smaller output voltage at the drain.
