Bluetooth is a wireless technology standard for short-wave length radio transmission of data for both fixed and mobile devices, thereby creating personal area network. This provides a secure communication between devices such as faxes, mobile phones, laptops, PCs, global positioning system receivers. An on-chip Phase Locked Loop (PLL) for Bluetooth application is specified in this paper. The closed loop of the proposed PLL is stable. This phase locked loop was designed with a digitally controlled oscillator, a phase detector, loop filter and a divide by N counter. The phase locked loop is simulated to have a lock in range of 2430MHz to 2470MHz.
