Phase locked loop for bluetooth radio

Phase locked loop for bluetooth radio / Anbalagan Loganathan
“Phase locked loop” merupakan satu sistem litar tertutup yang diguna pakai dalam banyak aplikasi untuk pelbagai fungsi. Manakala “Bluetooth” merupakan salah satu protokol piawaian untuk rangkaian tanpa wayar jarak dekat. Dengan menggunakan “Bluetooth” transmisi data boleh dibuat dengan objek statik atau bergerak. Sebuah “Phase Locked Loop Bluetooth” Radio telah dinyatakan dalam kajian ini. Rekaan sistem tertutup yang dicadangkan adalah stabil. “Phase Locked Loop”(PLL) yang direka merangkumi sebuah pengesan fasa dan frequensi (PDF), pam cas (CP), “Current- Starved” Voltan Pengayun Terkawal dan kaunter bahagi dengan 2. PLL disimulasikan dan lingkungan kunci ialah 28.57 MHz hingga 66.67 MHz. Frekuensi bebas untuk Voltan Pengayun Terkawal ialah 589.74 MHz. Masa mengunci ialah masa diambil oleh PLL mencapai hasil yang stabil. Masa mengunci untuk projek ini ialah 110 ns. PLL dari projek ini boleh menghasilkan isyarat dalam frekuensi 2.41 GHz dengan “duty cycle” berjumlah 51% apabila isyarat denyut berfrekuensi 50 MHz dibagi sebagai input. _______________________________________________________________________________________________________ Phase locked loop is a closed loop system and is being used in many applications for various purposes. While Bluetooth is one of the four protocol standard for short range wireless networks. With Bluetooth data transmission can be done either in fixed or mobile devices. A Phase Locked Loop Bluetooth Radio is specified in this study. The close loop in the design proposed is stable. This Phase Locked Loop (PLL) was designed with Phase Frequency Detector (PFD), Charge Pump (CP), Current-Starved Voltage-Controlled Oscillator, and Divide-By 2 counter. The Phase Locked Loop is simulated and the lock in range is from 28.57 MHz to 66.67 MHz. The free running frequency of Voltage Controlled Oscillator is 589.74 MHz. The lock in time is 110ns which is the time taken for the Phase Locked Loop to achieve a stable output of 2.41 GHz. This Phase Locked Loop can produce a 2.41 GHz frequency signal with 51% duty cycle when a 50 MHz pulse signal is given as input.
