“…In this case, the frequency shift reference is equal to 1160.8 MHz. Both sets of data points have been fitted according to the expected quadratic law [1]-Locking Threshold proportional to frequency shift squared-showing good agreement.…”

“…In order to verify the predictions of our previous theoretical analysis of the BPSK to ASK converter performance [1], two main dependences have been studied: first, the dependence of the BPSK to ASK conversion on the injected power and, second, the dependence of the conversion process on the transit time (i.e., maximum fall and/or rise time of the BPSK phase change). Due to the easy of measuring of the hybrid converter, both studies have been carried out using this implementation.…”

“…Let us now consider that the injected signal is a BPSK signal. According to our previous theoretical analysis [1], provided the locking frequency is in between the free-running frequencies of both ILOs, every phase shift at the BPSK input will cause a phase change in at the output of one of the ILOs and at the output of the other one. Thus, if the converter was in the "in-phase" state, it will evolve toward the "counter-phase" state and vice versa.…”

“…It is important to remark that the interval defines the conversion channel. BPSK signals, of which carriers are outside this frequency range, will not be converted because both ILOs will increase or decrease their phases simultaneously and no interference pattern will be produced at the converter's output [1]. Moreover, according to the results of Fig.…”

“…N PART I of this paper [1], a new method to convert binary phase-shift keying (BPSK) signals into amplitude-shift keying (ASK) signals based on the use of second harmonic injection-locked oscillators (ILOs) has been presented. The dynamic behavior of injected oscillators as a response to phase changes of the input signal has been analyzed in detail.…”

Abstract-This paper demonstrates the feasibility of a new circuit for the conversion of binary phase-shift keying signals into amplitude-shift keying signals. In its simplest form, the converter circuit is composed by a power divider, a couple of second harmonic injection-locked oscillators, and a power combiner. The operation of the converter circuit relies on the frequency synchronization of both oscillators and the generation of an interference pattern by combining their outputs, which reproduces the original phase modulation. Two prototypes of the converter have been implemented. The first one is a hybrid version working in the 400-530-MHz frequency range. The second one has been implemented using multichip-module technology, and is intended to work in the 1.8-2.2-GHz frequency range.Index Terms-Amplitude-shift keying (ASK), CMOS analog integrated circuits, converters, injection-locked oscillators (ILOs), multichip modules (MCMs), phase shift keying.

To deliver data at hundreds of megabits per sec over wireless media with high accuracy requires high signal acquisition and synchronization speeds. Many techniques have been developed in the past and choice of a right synchronization technique has become user and application specific. In this paper, we present our recent progress on the development of synchronization techniques, first, by reviewing the present techniques and then by presenting our work on using injection-locked techniques. Our work include the second-harmonic injection-locked phase-locked loop (SH-ILPLL) for BPSK signal demodulation with wide locking range, a singlefrequency ILO for high speed 160Msps QPSK detection and a selectable frequency dielectric resonator oscillator (SF-DR-ILO) based synchronization for coherent demodulation of multi-frequency QPSK signals of up to 63Msps. Our novel synchronization techniques can be used for modern communication systems such as WiMax or UWB applications. They can also be used for a fixed frequency or multiple-frequency high data rate video transmission over the indoor reciprocal channel.
