Abstract :
Noise reduction techniques based on both feedback and feedforward topologies have been employed over the last few decades to improve phase and amplitude noise of devices and oscillators. Various techniques, both historical and state-of-the-art, are compared in terms of noise performance, circuit complexity and applicability. A comprehensive reference list is included
