Abstract: The invention relates to a method of manufacturing integrated circuits, in which a variety of masks is used for manufacturing material layers, among which masks a suitable mask is selected to check the manufacturing quality of the component areas manufactured on the previous layer on the basis of the measurement results. Thus, the value of the component to be manufactured can be tuned to fit into the desired range and the range of the electrical values of the components of integrated circuits can be decreased. The component can be tuned in a variety of ways, e.g. by manufacturing components of different sizes and selecting a suitable component among them (158, 160, 162).

Abstract: A method and device for avoiding adjacent channel interference and reducing disconnections caused thereby, during communication between a mobile device and a base station in a wireless telecommunications network. The mobile device measures the strength of a received signal before the signal enters one or more selected filters, and compares the strength of the signal after the filtering, in order to estimate a power ratio of the adjacent channel interference to communication channel power. If the power ratio is greater than a threshold, then a handover is requested to an alternative communication channel available between the mobile device and either the base station or another base station.

Abstract: A method of using an integrated circuit with at least one defect, said method comprising the steps of determining the location of one or more defects in said integrated circuit; selecting a program to be stored on said integrated circuit, said program being selected on the basis of the location of said one or more defects; and loading said program onto said integrated circuit.

Abstract: In order to limit the heat dissipation within a regulator for controlling the supply to the microprocessor control unit of a communications device, a dropping component is connected in series with the regulator during periods of high battery voltage and is shunted during periods of low battery voltage in the battery charge cycle.

Abstract: A wireless communicator, such as a cellular telephone or personal communicator, includes a power source (e.g., two series connected batteries) providing output voltages VSS, VDD, and V1, where V1=(VDD-VSS)/2. The power source is coupled to a first load for powering the first load with VSS and VDD. The wireless communicator further includes a power source switching unit having first inputs coupled to VSS, VDD and V1, a second input coupled to a MODE signal, and outputs coupled to a second load. The power source switching unit is responsive to a first state of the MODE signal for powering the second load with VSS and V1, and is responsive to a second state of the MODE signal for powering the second load with V1 and VDD. By periodically toggling the MODE signal, such as at a frame rate of the wireless communicator, the power drawn from each battery by the second load is equalized, while providing the second load with a desired lower operating voltage.
