SUMMARY
This discussion focuses on designing a 100MHz Voltage Controlled Oscillator (VCO) using feedback and negative resistance methods. The user seeks guidance on identifying the operational results of the oscillator using Advanced Design System (ADS) by Agilent, a simulation software comparable to PSpice and Multisim. The design is centered around a Colpitts oscillator feedback model, with a frequency range of 100MHz to 500MHz. Key considerations include the type of VCO (monolithic or constructed with transistors and a varactor diode) and the requirement for a sinusoidal output.
