This paper realized a charge pump phase locked loop (CPPLL) frequency source circuit based on 0.15 μm Win GaAs pHEMT process. In this paper, an improved fully differential edge-triggered frequency discriminator (PFD) and an improved differential structure charge pump (CP) are proposed respectively. In addition, a low noise voltage-controlled oscillator (VCO) and a static 64:1 frequency divider is realized. Finally, the phase locked loop (PLL) is realized by cascading each module. Measurement results show that the output signal frequency of the proposed CPPLL is 3.584 GHz–4.021 GHz, the phase noise at the frequency offset of 1 MHz is −117.82 dBc/Hz, and the maximum output power is 4.34 dBm. The chip area is 2701 μm × 3381 μm, and the power consumption is 181 mw.

Analog-mixed signal (AMS) circuits are widely used in various mission-critical applications necessitating their formal verification prior to implementation. We consider modeling two AMS circuits as hybrid automata, particularly a charge pump phase-locked loop (CP-PLL) and a full-wave rectifier (FWR). We present executable models for the benchmarks in SpaceEx format, perform reachability analysis, and demonstrate their automatic conversion to MathWorks Simulink/Stateflow (SLSF) format using the HyST tool. Moreover, as a next step towards implementation, we present the VHDL-AMS description of a circuit based on the verified model.

Phase Locked Loops are key blocks which are widely adopted in all area of electronics, especially transceivers in wireless communication systems. The application of Phase Locked Loop varies from generation of local oscillator signal for upconversion and down conversion, generation and distribution of clock signals and jitter reduction. The most extensive use of Phase Locked Loop is for frequency synthesis. The requirements of synthesizer architectures depend on various system requirements and specifications which are based on regulatory standards. The design of Phase Locked Loop components involves the consideration of various techniques to resolve the nonidealities at front end high frequency components as well as back end low frequency components. This paper presents the background and importance of a Phase Locked Loop, various approaches over the years, design choices for each block and practical design methodology for Charge Pump Phase Locked Loops. This paper also presents the system level design of Phase Locked Loop and supply noise interactions among sub modules inside a charge pump Phase Locked Loop
