发明名称 DIODE FUNCTION GENERATER CIRCUIT
摘要 PURPOSE:To eliminate the restriction to generate a function approximated by linear segments by respectively forming linear function generation circuits, comparators, switching circuits, and a control circuit of circuits using no diode utilizing parasitic transistor effects, and switching linear functions by detecting the intersection of each linear function. CONSTITUTION:The linear function generation circuits 1A and 1B are respectively provided with amplifiers A1 and resistances R1, R4 and, by changing the values of the resistances R1-R4, etc., signals of desired linear functions are obtained from the circuits 1A and 1B. The switching circuits 3A and 3B are respectively constituted of CMOS transfer gates using transistors Q1 and Q2 and switching of the circuits 3A and 3B are performed by means of the control circuit 4A constituted in an inverter I1. Therefore, a diode utilizing a parasitic transistor effect is not required for constituting each section. Thus restriction to the extent of a generated function can be eliminated.
