Abstract

PURPOSE: To secure a fixed current ratio between the charge and discharge and thus to simplify the circuit constitution, by making the capacitor charge or discharge with a fixed amount of current from the reference voltage for the period the input signal has synchronization and then securing the dishcarge or charge to the reference voltage with the fixed current for the capacitor.
CONSTITUTION: Capacitor 1 change or discharges with a fixed current from the reference voltage for the period the input signal has synchronization. Then capacitor discharges or charges with the fixed current to the reference voltage. Thus, the division ratio is determined by the ratio of the fixed current between the charge and discharge
