Abstract
In order to enable non-integer current ratios to be produced in current mirror circuits using small transistors the channel area is adjusted by changes in the channel length over part of the width of the channel. In further embodiments the transistor is formed as two or more sub-transistors, the channel length of one sub-transistor being unequal to that of the other(s).
Claims4
A MOS transistor having a channel comprised of first and second segments connected in parallel, the first segment having a first width and a first length, and the second segment having a second width and a second length, wherein the first and second lengths are different, and the first and second widths are different.
