Abstract: A delay lock loop includes a phase frequency detector, a loop filter, and a voltage controlled delay circuit. The phase frequency detector is used for outputting an upper switch signal or a lower switch signal according to a reference clock and a feedback clock. The loop filter includes a first capacitor, a second capacitor, and a first switch. The first capacitor is charged or discharged and the first switch is turned off during a phase tracking period. The first capacitor and the second capacitor are charged or discharged and the first switch is turned on during a phase locking period. The voltage controlled delay circuit is used for outputting the feedback clock according to the reference clock and a control voltage outputted by the loop filter.

Abstract: An immediate response low dropout regulation system includes a low dropout regulation unit, a tracking voltage generation unit, and a self-driving unit. The low dropout regulation unit is used for generating and outputting an inner output voltage according to a reference voltage. The tracking voltage generation unit is used for generating and outputting a tracking voltage according to the reference voltage. The self-driving unit is coupled to the low dropout regulation unit and the tracking voltage generation unit. When a voltage difference between the tracking voltage and the inner output voltage is greater than a constant times threshold voltage, the self-driving unit provides a compensation current to an output terminal of the low dropout regulation unit.
