“…This synchronization regime presents common features with harmonic (M = 1) [6,7,12,13], and with sub-harmonic synchronization (N = 1) [14,15]. Therefore, for a given value of the reference signal power, the synchronization range depends on the harmonic content and the quality factor of the circuit [16].…”

Abstract-In this work, a nonlinear technique for the optimization of the synchronization bandwidth of Rationally Synchronized Oscillators (RSO) is presented. The circuit is forced to operate near a Hopf bifurcation point which is created around the frequency of the input reference signal. Under this operating regime, the reference signal is strongly amplified and the synchronization bandwidth of the circuit is considerably improved. A 5-3 GHz rationally synchronized oscillator has been optimized using the proposed method. The manufactured RSO provides a 5 MHz synchronization bandwidth with a reference signal power of −22 dBm, in good agreement with simulation results.

“…Despite of the good performance demonstrated by the harmonic optimization technique described in [16], when high synchronization order is considered, with M > 2, a relatively high value of the reference signal power is required in order to get a value of V M r enough to obtain a synchronization range usable in practice.…”

“…A novel approach to design a Tx-Rx multicarrier system with capability of phase variation determination, based on Rationally Synchronized Oscillators (RSO) [13,14], is described in this paper. The RSO is a very compact and low cost circuit, since it is based on a single transistor and a reduced number of components.…”

Abstract-In this work, a novel multi-carrier Tx-Rx system based on rationally synchronized oscillators to be used in RF-source localization applications is presented. The Tx subsystem is composed by two rationally synchronized oscillators, with different operation frequency, which share the reference signal. This signal is transmitted together with the one generated by the oscillators. In the Rx subsystem, the reference signal is provided by an oscillator which is synchronized with the received reference signal. According to the simulation results, with the proposed approach, the determination of the relative phase variation suffered by the transmitted signals, due to the propagation channel, can be achieved with an error less than 0.6 • . It is also shown that the dynamic response of the system can be optimized by properly selecting the operation point of all oscillators.

“…Over the last years, the increasing demand of low cost compact microwave systems with high functionality and low DC-power consumption [1,2], has motivated the development of different techniques for the harmonic optimization of microwave circuits [3][4][5][6][7][8]. Circuits with an optimized harmonic content require DC feeding networks that avoid the power transfer to the DC-source at these harmonics.…”

Abstract-In this work, we present a novel DC-bias network for multiharmonic microwave circuits based on an arbitrarily width-modulated microstrip line. The arbitrary shape of the width-modulated microstrip line is obtained by using multiple microstrip taper sections. The method is illustrated through the design of four different DC-bias networks blocking from 1 to 4 harmonic components of a 2.5 GHz signal. The designs with an optimum shape for the arbitrarily widthmodulated microstrip line have been manufactured and measured, obtaining a good agreement between the simulated and measured behavior.
