  • Patent number: 10706209
    Abstract: Roughly described, a system for estimating an effective channel length of a 3D transistor having a gate length below 20 nm involves estimating an effective volume of the channel and a cross-sectional area of the channel, and estimating the effective channel length as the ratio of effective volume to cross-sectional area. Preferably the effective volume is estimated as the sum of the Voronoi volumes within containing boundaries of the channel, excluding those volumes having a dopant concentration above the source/drain dopant concentration at the carrier injection point. The containing boundaries can be identified using geometry data describing the transistor, particularly the data identifying inner surfaces of the gate dielectric. The estimated effective channel length can be used in TCAD level analysis of the transistor and calculating characteristics of the transistor as needed for circuit simulation.

  • Publication number: 20200213953
    Abstract: Novel techniques for pooling the available transmit power of a beam across the subcarriers that are or that are scheduled to be in use (and not across all available subcarriers) are disclosed. The scheduled subcarriers may be located in the same or different carriers of a modulation transmitter modulation system, and the pooled transmit power may be allocated or distributed across the scheduled subcarriers of the beam. Modulation symbols or resource elements may be transmitted in accordance with allocated, per-subcarrier power budgets, thereby maximizing the SNIR of signals that are transmitted in the beam via the scheduled subcarriers. Additionally, the allocation of the pooled transmit power to various subcarriers may continuously and/or dynamically vary over time, e.g., based on traffic demands, interference characteristics, etc., as well as based on subsequent scheduling of subcarriers to transmit subsequent modulation symbols or resource elements.
