WebBecause the voltage difference between the source voltage (Vs) and body voltage (Vb) affects the Vt, the body can be thought of as a second gate that helps determine how a … Web• As the drain voltage increases, the reverse bias on the body‐drain PN junction increases, and hence the drain depletion region widens. ÆVTH decreases with increasing drain bias. (The barrier to carrier diffusion from the source into the channel is reduced.) ÆID increases with increasing drain bias.

WebMar 10, 2003 · This paper addresses misconceptions about MOSFET mismatch for analog design. V/sub t/ mismatch does not follow a simplistic 1/ (/spl radic/area) law, especially for wide/short and narrow/long devices, which are common geometries in analog circuits. Further, V/sub t/ and gain factor are not appropriate parameters for modeling mismatch.
