A low-voltage low-power CMOS phase-locked loop (PLL) is presented in this paper. It consists of a phase frequency detector, a charge pump, a loop filter, a voltage-control oscillator, and a frequency divider. A new phase frequency detector is proposed to reduce the dead zone and the mismatch effect of the charge pump circuit. A novel charge pump circuit with a small area and wide output range is described. The PLL circuit has been designed using the TSMC 0.35 μm 1P4M CMOS technology. The chip area is 1.08 mm × 1.01 mm. The post-layout simulation results show that the frequency of 900 MHz can be generated with a single supply voltage of 1.5 V. The power dissipation of the circuit is 9.17 mW.

This paper proposes design and implementation of low power Delay Locked Loop Architecture, with dynamic Multiplexer based Phase Frequency Detector with minimum locking time. Clock and data recovery systems are employed to derive the clocking information to correctly decode the transmitted data at the receiver. Delay Locked Loop is one of the most important clock recovery systems. The DLL architecture is designed using Cadence Virtuoso 180nm Technology with 1.8V power supply. The proposed DLL with Multiplexer based phase frequency detector shows significant reduction in power dissipation by 10% compared to DLL designed using D-FF based PFD and achieves locking state within 10 clock cycles with minimum jitter of 4.84326ps, measured within clock frequency range of 100-250MHz.

Aims: A high performance low power phase frequency detector is designed and simulated. The various different parameters of the circuit are obtained through various type of simulations. We worked mainly upon the power dissipation, power supply, input frequency range and its area. The proposed PFD will have the locking capability i.e. to lock at the edges either on the rising or falling edge w.r.t the reference and the feedback signal. The proposed design will have the very high performance and ultra-low phase noise. It has the added advantage of low cost and the compact size. Objective: The primary objective is to design a low power phase frequency detector for CMOS PLL Frequency Synthesizer using lows power technique. Method: The pass transistor logic is used in the circuit to eliminate the reset path. By this change of the path the operating frequency and operating speed both are increased in the proposed design. The input Frequency can be taken up to 5 gigahertz. The power supply is taken to be 1 V. The proposed PFD design will have a less number of transistors and also a low consumption of power. The output pulses of the PFD at phase difference of 0, 0,п/2, п, 3п/2, 2п will have its average voltage as 0, VDD and VDD/2. The proposed phase detector will perfectly detect the phase difference between two signals so that the harmonics problem can be minimized. Result: The proposed design is having its operating frequency as 5GHz over the conventional one which has its frequency as 800MHz. Power dissipation in the proposed design is reduced due to less number of transistors used as compared with the conventional one. The operating region has become much wider for proposed design as it is having operating frequency much higher than that of the conventional one. Conclusion: The proposed PFD will increase the locking capability on the both rise and fall edge w.r.t. the reference and the feedback signal. The input Frequency can be taken up to 5 gigahertz. The power supply is taken to be 1 V. The proposed PFD circuit will have a less number of transistors and also a low consumption of power 7.14 mW.
