摘要:
In one embodiment, the invention includes a field effect transistor having a substrate (54), a source (S1), and a drain (D1). An electric field terminal region (52) is in the substrate. A body (64) is above the electric field terminal region between the source and drain. There is a barrier (58) between the electric field terminal region and the body. In a similar embodiment, the invention includes a field effect transistor having an insulator layer (58) and a body above the insulator layer between a source and a drain. A substrate is below the insulator layer. A gate (G1) is above the body and between the source and drain. An electric field terminal region is included in the substrate. The body may be undoped and the threshold voltage be set by setting the distance between the insulator layer and a gate insulator. The body, substrate, and electric field terminal region may float or one or more of them may be biased.

Alternately skewed gates (1509) to reduce signal transmission delay. For one embodiment, an integrated circuit includes a chain of gates (1505, 1506, 1507, 1508) alternately skewed for fast rise and fast fall. Pulse encoding logic (1510) coupled to the chain of gates pulse encodes a signal to be provided to and transmitted by the chain of alternately skewed gates.

Under one aspect of the invention, a semiconductor circuit (50) includes a first group of field effect (FET) transistors (60 and 62) of a first type (p-type) each having a body and a gate. The circuit includes a second group of field effect (FET) transistors (54 and 56) of a second type (n-type) each having a body and a gate. The circuit includes a first voltage source to selectively provide a forward bias to the bodies of the first group of FET transistors (60 and 62) during a first mode and to provide a non-forward bias to the bodies of the first group of FET transistors (60 and 62) during a second mode, and while in the first mode, the forward bias (68) is applied to the bodies of the first group of FET transistors (60 and 62) independent of voltages (A and B) applied to the gates of the first group of FET transistors (60 and 62). Under another aspect of the invention, a circuit (310) includes p-channel field effect transistors (pFET transistors) having n-type bodies electrically coupled to the ground voltage node to forward body bias the pFET transistors. A circuit includes N-channel field effect transistors (nFET transistors) having p-type bodies electrically coupled to the supply voltage node to forward body bias the nFET transistors.
