高频回路设计Sheet 1 of 26 Oscillator Basics Tutorial J P Silver E-mail: john@rfic.co.uk ABSTRACT This paper discusses the basics of oscillator design including the parameters effecting oscillator performance, with special emphasis on the causes of phase noise. Theory is given for the two types of oscillator topography namely feedback and reflection oscillators. the device, which is not far from the 1dB compression point. A diagram of a typical compression characteristic, for the device used as an amplifier, is shown below in Figure 1. Output power Saturated output power INTRODUCTION This tutorial shows how device parameters can effect the performance of oscillators, including output power, oscillating frequency and probably most important of all ……
