Abstract

The synchronous oscillator (SO) is a network capable of recovering signals down to -100 dBm. Its output amplitude is independent of the input amplitude and is constant. Without an input signal, the SO free runs at a frequency ω₀, determined by the L- C-C tank parameters. The coherent phase synchronous oscillator (CPSO) is a modification of the SO and retains the SO properties of high noise rejection and fast acquisition time. Advantages of the CPSO are a coherent signal acquisition and a much wider tracking bandwidth. An analysis of the SO and CPSO is performed to explain the coherent signal processing that occurs in the CPSO. Such an analysis also sheds light on the design and calibration of the CPSO
