发明名称 METHOD OF LASER TRIMMING SIMULATION
摘要 <p>PURPOSE:To make it possible to cut down the developing period of time as well as to reduce the cost of developement by a method wherein the other end side of an offset resistor is connected to common one end side of a network resistor, and the individual other end side of said network resistor is connected individually to the end part on the other side of both end parts of the common end side through a changeover contact point respectively. CONSTITUTION:One end side 14c of an offset resistor RO is connected to the end part 14a on one side located between both end parts 14a and 14b of a simulation resistor part 14, and at the same time, the other end side 14d of said offset resistor RO 14d is connected to the common one end side 14e of a network resistor NR. The individual other end sides 14fl to 14fx of the network resistor NR are individually connected to the end part 14b located on the other side of both end parts 14a and 14b of the network resistor NR through the intermediary of change-over contact points S1 to Sx. The changeover contact points S1 to Sx are ON-OFF controlled by a resistance value change-over device 16.</p>
