SpletA Voltage Controlled Oscillator (VCO) is a critical building block in the design of current frequency synthesizers for RF system applications. State-of-the-art operation defines that an oscillator should have the best spectral purity while consuming low amount ... Figure 34: Single-switch capacitor for coarse-tuning: (a) schematic; (b) equivalent Splet31. maj 2015 · In my VCO design, if I introduce a fixed capacitance, Cap_fix into the C tank, it works fine and give me the target frequency I want. If I disconnect this path (in parallel with the total C) to disable the introduction of this Cap_fix, it gives me higher frequency and it is reasonable as it follows： w = 1/sqrt(C*L).

SpletDisabling either VCO of the 'LS625 and 'LS625 and 'LS627 can be achieved by removing the appropriate OSC V CC. An enable input is provided on the 'LS624, 'LS626, 'LS628, and 'LS629. When the enable input is low, the output is enabled: when the enable input is high, the internal oscillator is disabled, Y is high, and Z is low.
