The first is the direct sample and hold circuit. When the sample and hold oscillator is high, and the switch is closed, the VCO tracks the pitch oscillator, and when the S&H oscillator goes low ...

The demand for analog and mixed-signal-based integrated circuits (ICs) has surged due to the increasing reliance on electronic-based applications across industries. As the world transitions to more ...

The keyboard interface circuit is clever ... voltage to drive the synth’s voltage-controlled oscillator (VCO). The video below shows what it can do. We love projects like these because they ...

Output jitter is commonly caused by jitter on the reference clock or by sensitivity in the VCO and other circuits to noise sources both inside the PLL block, such as thermal noise and flicker noise, ...
