摘要： Inductive structures make highly efficient use of the magnetic flux generd, and are consistent with integrated circuit manufacturing techniques. The structures include electrically conductive layers and interconnecting conductor filled vias to define a helical winding surrounding a closed magnetic core. The magnetic core may also be formed by semiconductor manufacturing techinuqes. A method of making the structures on a semiconductor substrate concurrently with the formation of the integrated circuit itself is also disclosed.

摘要： A reduced area delay circuit and method are disclosed. The delay circuit uses a constant current source and a constant current drain to charge and discharge a capacitor and thus control the delay time of the delay circuit. The constant current source and drain can be implemented using current mirrors formed by configuring MOSFET transistors in a common source configuration. The delay circuit method includes the steps of receiving an input signal, delaying the input signal by using a constant current source or drain in combination with a capacitor, and then buffering the voltage on the capacitor using two inverters. A programmable delay circuit is also disclosed by adding additional pairs of current mirrors to the delay circuit and selectively enabling the pairs to adjust the delay time.

摘要： An integrated analog circuit having a circuit topology and intrinsic characteristics which may be selected by digital control means is formed by batteries of similar circuit components arranged substantially in parallel or in a matrix array, anyone of which may be isolated or not by means of a dedicated integrated switch and by alternative interconnection paths among the different circuit components and/or batteries of circuit components, which may be also be selected by closing a relative integrated switch. A dedicated nonvolatile memory, integrated on the same chip may be permanently programmed and determine a certain configuration of all the integrated switches thus selected a particlar component or more components of each of said batteries of functionally similar components, and/or selecting a certain interconnection path among the different circuit components in order to form a functional integrated circuit having the desired topology and intrinsic characteristics. The integrated nonvolatile memory is programmed by means of a software program which may take as input data the desired values of the different parameters which determine the intrinsic characteristics of the functional analog circuit and the type of functional analog circuit itself.
