Abstract: PROBLEM TO BE SOLVED: To miniaturize the layout of circuitry necessary for fusing a programmable fuse by providing an integrated circuit fuse weakening the fuse or including a shape changing the fuse by other methods. SOLUTION: A pair of via holes 22 is formed adjacent to a fuse 20 so as to cross the selected part of the fuse 20. As the result of a process used for manufacturing an integrated circuit related to the fuse 20, a contracted part 23 is formed by the fuse 20 between the via holes 22. Thus, the via holes 22 can be set to various forms and sizes according preference to manufacture a contracted part 23 of desired form, size and number. The fuse 20 of the contracted part 23 is changed so that the fuse 20 can be operated with a current smaller than the current quantity required to blow out the fuse 20 in the unchanged state.

Abstract: PROBLEM TO BE SOLVED: To reduce the integrated circuit area of a multiplier for the multiplication of a filter coefficient to filter a diffusion data stream for transmission in a broad band code division multiple access(WB-CDMA) communication system. SOLUTION: A system is provided with a step 702 for executing filtering by a raised cosine(RRC) filter using one-bit multiplier in a plurality of diffusion user data streams and a step 703 for connecting the plurality of user data streams being the sequence of one-bit value. The RRC filter filters the diffusion user data streams before or after the connection of the diffusion user data streams through the use of an FIR filter including one-bit coefficient or a multi- bit coefficient.

Abstract: PROBLEM TO BE SOLVED: To simplify constitution by providing an array of resistors, which are composed of resistances coupled to a reference power source in series and generate analog voltages at respective taps and coupling multiple sets of multiple switches coupling desirable taps and an output node with a coded signal to one resistor array in common. SOLUTION: A resistor array 14 is composed of resistances R1 to Rn coupled with the reference power source 12 in series and generate necessary analog voltages at respective taps T1 to Tn+1. Switches M11 to Mn+11 forming a 1st switch S1 receives the control signal from a switching transistor selecting and drive circuit 18 and sends the analog voltages of the corresponding taps T1 to Tn+1 to a 1st output node 16. Then 2nd, 3rd, etc., sets of switches S1, S2, etc., receive control signals from respective switching transistor selecting and drive circuits 28, 38, etc., and send the corresponding analog voltages to 2nd, 3rd, etc., output nodes 26, 36....
