Assignment on Oscillators

Design and simulation:

Design a Colpitts oscillator with a oscillation frequency of 70 MHz if possible with maximum

output power. Simulate the oscillator with ADS. Determine the harmonics frequency and amplitude

with respect to fundamental. Determine the phase noise at 1KHz offset and 10 kHz. Convert the

oscillator to a tunable oscillator with a varactor.

Design a 800 MHz oscillator with a negative power supply. Simulate with ADS. Determine the

harmonics and phase noise. If possible, convert it to a tunable oscillator using varactor.

3) Design a differential LC oscillator at frequency 500MHz. Simulate the response with ADS.
