  • Publication number: 20230359796
    Abstract: A system and method for performing circuit design analysis obtains a circuit design comprising cells. The cells are associated with cell types. Aging parameters of a core analytical model are determined for each of the cell types in the circuit design to generate a calibrated analytical model. Aging effects for the cells are determined based on the calibrated analytical model and target stress conditions. An aged timing model is determined for the cell types based on the aging effects, an unaged timing model, and the target stress conditions.

  • Patent number: 7650271
    Abstract: In general, in one aspect, the disclosure describes a simulator for emulating various types of device noise in time-domain circuit simulations. The simulator is capable of adding noise to transistors as well as passive elements like resistors. The simulator utilizes at least one current source in parallel to a device to emulate the noise. The current source generates a random current output to emulate the device noise based on a random Gaussian number and the standard deviation of the device noise. The noise standard deviation can be determined based on the noise power spectral density of the device having a particular bias at that simulation time and the update time. The simulator is capable of emulating any noise source with a constant or monotonically decreasing noise spectrum (e.g., thermal noise, flicker noise) by utilizing multiple current sources having different update steps. The simulator is compatible with standard circuit simulators.

  • Publication number: 20080079051
    Abstract: A metal oxide semiconductor varactor may be formed with HALO implants regions having an opposite polarity from the polarity of the well of the varactor. The HALO implant regions can be angled away from the source and drain. The HALO implant regions can stop the depletion from continuing as the bias voltage applied to the gate continues to increase. Stopping that depletion can create a constant capacitance when the varactor is in a depletion bias.
