Phase-Locked Loop Circuit Design Dan H. Wolaver
Publisher: Prentice Hall

A crunchy analogue sounding bit-crushing synthy thing i kept to the philosophy (in tweaking the previous design) to make sure it had the widest variance i could achieve in the pll circuit for each knob without compromising the original sputter that i fell in love with in the first place. The end of your audio is saturated in tails of sputtering electricity sounds. *While this version used vacuum tubes, it's latter implementation used semi-conductors. Cosmic Circuits today announced that its PLL solutions are being used by Enverv, a provider of advanced SoC solutions for smart grid, metering and control applications. The Silicon Creations Fractional-N PLL (block diagram shown in Figure 2) suppresses this noise with the addition a feed-forward compensator that feeds directly into the loop filter, and is able to achieve jitter in Fractional mode very close to that achieved in integer mode. A complete overview of both system-level and circuit-level design and analysis are covered. This is the simple electronic siren schematic, built using three ICs: CD4011 NAND gate logic, CD4066 Bilateral Switch and CD4046 Micro power Phase-Locked Loop (PLL). This book presents both fundamentals and the state of the art of PLL synthesizer design and analysis techniques. Long term jitter as small as 2ps RMS has been Thus the PLL Period Jitter (PJ, also known as short term jitter) must be known in order for the circuit to have sufficient timing margin. Each of these applications demands different characteristics but they all use the same basic circuit concept. Figure 1 contains a block diagram of a basic PLL frequency multiplier. In a PLL circuit, the number of LPFs is reduced to one to reduce mounting area and pin number, and to simplify design. That's a diagram of his version to the upper right. A PLL is a solid-state tuner: no tubes*, no crystals, no nada.
