Astable Multivibrator with Voltage-Controlled Variable Duty Cycle

Applications of Timer Integrated Circuits

“…Finally if v = u = constant, the circuit acts as conventional astable multivibrator; however the present circuit provides complementary outputs. x Inverse duty cycle operation transistorized circuit that appeared earlier [27]. These duty cycle circuits may be useful in speed control of dc motors [9] [28] and switched-capacitor filters.…”
