DC FUNCTION GENERATOR REALIZING SQUARE-LAW DEPENDENCE Russian patent published in 1996 - IPC

FIELD: analog computer equipment, measuring instruments for enhancing accuracy of conversion and simplifying the process of tuning. SUBSTANCE: function generator has field-effect transistors 1, 2, operational amplifiers 3, 4, 11, 12, summer 5, resistors 6, 7, 13, 14, 15, AC voltage generator 9, converter 10 changing alternating voltage to direct voltage proportional to it, capacitors 16, 17, 18,19. Due to the respective couplings between the generator components provision is made for independence of the output signal proportional to the square of the input signal both on the temperature of the field-effect transistors and on the peculiarities of their volt-ampere characteristics. EFFECT: enhanced accuracy of conversion. 1 dwg
