Abstract: A phase locked loop having a stack structure for low power is provided to remove a power noise caused by a parasitic inductance generated in current mirroring by not using a current mirror circuit. A phase locked loop having a stack structure for low power includes a voltage controlled oscillator(120), and a divider(110). The voltage controlled oscillator is located on a ground terminal and an operation power terminal for supplying a predetermined operation power, and generates an oscillation signal. The divider is electrically coupled to the voltage controlled oscillator in series between the operation power terminal and the ground terminal. The divider generates a division signal which divides an oscillation signal of the voltage controlled oscillator. The voltage controlled oscillator and the divider form a transmission path of the operation current which flows between the operation power terminal and the ground terminal.

A differential oscillation part(200) includes first and second transistors(M10,M20) outputting an oscillation signal by oscillating the resonant frequency of the resonant circuit part by being differentially cross-coupled to the resonant circuit part. A peak detection part(300) detects a peak value of the oscillation signal of the differential oscillation part, and outputs a peak detection voltage by adding the power supply voltage and a detected voltage. An inverter(400) converts a control voltage with a lower voltage level than the tuning voltage into the tuning voltage having a voltage level of the peak detection voltage according to the peak detection voltage.
