Design and Implementation of a Novel Frequency Modulation Circuit Using a Phase-locked Loop Synthesizer

A phase-locked loop (PLL) is widely used in frequency synthesizers for modern communication systems. However, frequency modulation (FM) of a PLL for the modulation rates used inside the loop bandwidth, is generally difficult. In this article, a novel b...

A phase-locked loop (PLL) is a popular method used in frequency synthesizers for most communication systems. 10 The block diagram of a common PLL synthesizer is shown in Figure 1 and includes a charge pump phase detector (PD), a temperature-compensated crystal oscillator (TCXO), a voltage-controlled oscillator (VCO), an R...
