Abstract:The paper presents an Integer-N phase locked loop (PLL) for Bluetooth receiver implemented in CMOS 130 nm technology. The presented phase locked loop consists of an LC quadrature voltage controlled oscillator with capacitor bank, a tri-state phase-frequency detector with charge pump, a third order passive filter and a programmable divider. The PLL has a supply voltage of 1.2 V and dissipates 2.4 mW. The output frequency range of the phase locked loop is from 2.2 GHz to 2.8 GHz and phase noise is equal -124 dBm… Show more
