Abstract
According to one exemplary embodiment, a fin-based adjustable resistor includes a fin channel of a first conductivity type, and a gate surrounding the fin channel. The fin-based adjustable resistor also includes first and second terminals of the first conductivity type being contiguous with the fin channel, and being situated on opposite sides of the fin channel. The fin channel is lower doped relative to the first and second terminals. The resistance of the fin channel between the first and second terminals is adjusted by varying a voltage applied to the gate so as to achieve the fin-based adjustable resistor. The gate can be on at least two sides of the fin channel. Upon application of a depletion voltage, the fin channel can be depleted before an inversion is formed in the fin channel.
