200Mhz to 400Mhz Voltage Controlled Oscillator

Inverters form three-phase VCO

You sometimes need an inexpensive VCO that can produce evenly spaced three-phase outputs over a wide frequency range. This application uses unbuffered U-type inverters for use in ring oscillator setup which generates relatively squarish somewhat sine-like

Inverting latches make simple VCO

simple VCO circuit which is synthesized from inverting latch stages and is tunable to an integer multiple of the input frequency by selecting which output phases feed back to the input multiplexer, suitable to be usable as on-chip clock multiplication in

200-400MHz voltage controlled oscillator

produces clean emitter coupled logic (ECL) type signal between 200MHz and 400MHz
