    摘要: According to an aspect of an embodiment, a method of designing an analog circuit may include selecting multiple analog components for a circuit. The method may also include ordering the analog components. The method may also include determining at least one pareto-optimal design point for a parameter of each analog component. The pareto-optimal design point for each analog component may be based on a performance metric, the parameter for the respective analog component, and constraints resulting from pareto-optimal design points for analog components ahead of the respective analog component within the ordering of the analog components.

    摘要: A control apparatus for an automatic transmission includes a control section having a target secondary pressure setting section configured to set a target secondary pressure within a strength limit of the belt, and an operation switching section configured to switch a shift operation from a normal speed to a high speed higher than the normal speed when a predetermined condition is satisfied. The control section is configured to control the secondary pressure regulating valve by a feedback control based on the target secondary pressure and the actual secondary pressure sensed by the hydraulic pressure sensor. The target secondary pressure setting section is configured to modify the target secondary pressure by adding a predetermined quantity when a correction initiation condition is satisfied, the condition initiation including a first condition that the shift operation is performed at a high speed by switching of the operation switching section.
