Abstract
A fixed frequency clock generator generates and outputs a fixed frequency clock by using a number of fixed delay units and a number of inverters that both are connected in series alternately and evenly. More particularly, the fixed delay unit involves two fixed current sources and two controlling switchers, plus an inverter that controls a charging and a discharging of a capacitor. Then the electric potential of the capacitor and a stable voltage source respectively send the current to the comparator. The time of charging and discharging of the capacitor is fixed, therefore the time of the electric potential of the capacitor is fixed for reach to the fixed voltage source, and the sequence of the output signal of the comparator is also fixed. In the above description, the fixed delay unit generates the fixed frequency.
