Characterizing Phase Noise The term phase noise is widely used for describing short term random frequency fluctuations of a signal. Frequency stability is a measure of the degree to which an oscillator maintains the same value of frequency over a given time. This may...

Introduction Voltage controlled oscillators (VCOs) are normally designed for operation into ideal 50Ω impedance. Actual loads into which they work are seldom ideal. It is a standard industry practice to measure the variation of the frequency when the VCO output is...

Oscillator Fundamentals An oscillator circuit can be modeled as shown in Figure 1 as the combination of an amplifier with gain A (jω) and a feedback network (jω), having frequency-dependent open-loop gain H (jω) = ßA. Figure 1: An oscillator may be modeled as the...
