A phase-locked loop(PLL) with effectively increased capacitance by current modulator has been proposed. In this paper, the effective capacitance of loop filter is increased by using current modulator and it results in 1/10 reduction of capacitance in loop filter. It has been designed with a 1.8V CMOS process. The simulation results show that the proposed PLL has the same phase noise characteristic and locking time of conventional PLL.
