Abstract
The disclosure provides a delay line circuit including an output stage. The output stage includes a first inverter cell, a second inverter cell, a correction circuit, and a first switch capacitor array. The input terminal of the first inverter cell receives a reference clock signal. The input terminal of the second inverter cell is coupled with the output terminal of the first inverter cell. The first terminal of the correction circuit is coupled with the output terminal of the first inverter cell, and the second terminal of the correction circuit is coupled with a ground, wherein the correction circuit corrects a duty cycle of the delay line circuit. The first terminal of the first switch capacitor array is coupled with the output terminal of the second inverter cell, and the second terminal of the first switch capacitor array is coupled with the ground.
