Abstract: PURPOSE:To improve the control accuracy and the stability of a low current area without using complicated circuit constitution by reading the correction gain out of a ROM in accordance with a high-order bit address of the digital current set value and correcting the output of an error amplifier. CONSTITUTION:This unit is provided with a logic circuit 12 to extract the logic out of a high-order bit part of the digital current set value and a ROM 13 which stores the correction gain corresponding to an address, i.e., the output value of the circuit 12, and a D/A converter 9 which applies the D/A conversion to the output of an error amplifier 10 after correcting it with the correction gain. Then a driving circuit 11 of a transistor element 5 is driven with the output of the converter 9. Thus the correction gain is read out of the ROM 13 in response to the digital current set value and then multiplied by the output of the amplifier 10. Thus, the linear VIn-Ic characteristic is secured in an output low current area as long as the correction gain is set at a proper level. Thus it is possible to ensure the satisfactory control accuracy and stability in a wide current area covering a rated current area through a low current area with simple constitution.

Title: Logic simulation system
Inventor: TAKITA ISAO
IPC: G01R31/28
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To make it possible to shorten the simulation time by selecting a node, which affects a simulation result and limiting nodes, which are registered in a time wheel in consideration of a delay time at the time of the simulation. SOLUTION: Nodes, which possibly affect an operation result, are stored in a registered node storage part 112. If an event of a node occurs at certain time, a simulation event managing means 109 makes a registered node decision means 110 decide whether or not the node is registered by referring to the storage part 112 and feeds the result back to the managing means 109. When the decision means 110 decides that the node where the even occurs is not registered, the event of the node is not scheduled in an event storage part 113 (not registered in the time wheel), its logic is immediately updated, and elements of the next stage following the node as its input node are regarded as current objects of arithmetic. Consequently, the processes for registration and reference can be reduced.
