MOSFETp-Type surface conductive layerMetal–semiconductor (MES) field-effect transistors (FETs) and metal oxide–semiconductor (MOS) FETs are fabricated using p-type conductive layers on hydrogen-terminated diamond surfaces. The FETs exhibit complete channel pinch-off and drain-current saturation. Both...
VDB,eff is the drain-body voltage clipped to a maximum value corresponding to velocity saturation or pinch-off (whichever occurs first). Vp is the channel-length modulation voltage. The block computes the inversion charge densities directly from the surface potential. The block also computes the ...
In a long channel MOSFET, the width of the pinch-off region is assumed small relative to the length of the channel. Thus, neither the length nor the voltage across the inversion layer change beyond the pinch-off, resulting in a drain current independent of drain bias. Consequently, the ...
the negative charge from the channel closest to the drain is drawn into the drain, reducing the channel's width and so restricting charge flow. In addition, it lowers current flow. When we increase the voltage, the channel's entire contraction reaches a point known as the pinch-off effe...
In addition to high transconductance, the devices exhibit excellent pinchoff and demonstrate a record gate turn-on voltage of -3 V as a result of extremely low gate leakage currents, making them exceptional candidates for complementary technologies. These outstanding gate characteristics are attributed ...

With the increase of vDS, the channel near the drain becomes thinner and thinner. When vDS is increased to make VGD=vGS-vDS=VT (or vDS=vGS-VT), the channel appears pre-pinched off at the end of the drain , As shown in Figure 2(b). Continue to increase vDS, the pinch breakpoint ...
A simple analytical model derived from a quasi-two-dimensional analysis with a non-vanishing E-field derivative at the pinchoff point and a continuous output conductance at the transition point for short-channel MOSFETs is presented. Thi... HC Chow,WS Feng - 《Iee Proceedings Part G Circuits ...
