Phase noise characterization of subharmonic injection locked oscillators
نویسندگان
چکیده
In this work we present a detailed study of the phase noise of subharmonic injection locked oscillators (s-ILOs). A new simple and efficient model has been presented for accurately predicting the phase noise of a microwave s-ILO. The validity of the analytical technique is verified with measurement results obtained from a 5-GHz fully differential Colpitts-based s-ILO. The results showed that a phase noise improvement of 12 dB at 1 kHz offset frequency compared to the free-running case can be achieved, whereas the power consumption is 21mW.

The Transient Behavior of LC and Ring Oscillators under External Frequency Injection
In this work, time domain analysis is used to solve Adler’s equation in order to obtain the required time, for an oscillator under external injection, reaching the steady-state condition. Mathematical approach has been applied to fully describe the transient of frequency acquisition in injection-locked LC and Ring oscillators considering their time-varying nature. Then, the analysis is verifie...
متن کامل0 Theory of self phase - locked optical parametric oscillators
The plane-wave dynamics of 3ω → 2ω, ω subharmonic optical parametric oscillators containing a second harmonic generator of the idler-wave ω is analyzed analytically by using the meanfield approximation and numerically by taking into account the field propagation inside the media. The resonant χ(−3ω; 2ω, ω) : χ(−2ω;ω,ω) cascaded second-order nonlinearities induce a mutual injection-locking of th...
متن کاملA Novel Injection-Locked Oscillator MMIC with Combined Ultrawide-Band Active CombinedDivider and Amplifiers
A subharmonically injection-locked oscillator (ILO) MMIC for local oscillators, synthesizers, and phased-array antennas is proposed. An ultrawide-hand four-port active combineddivider in the oscillator feedback loop provides an FEToriented circuit topology extremely suitable for single-chip integration, and performs subharmonic injection locking at various subharmonic factors, l/n. Two types of...
متن کاملMicrowave Balanced Oscillators and Frequency Doublers
The research presented in this thesis is on the application of the injection-locked oscillator technique to microwave balanced oscillators. The balanced oscillator design is primarily analysed using the extended resonance technique. A transmission line is connected between the two active devices, so that the active device resonate each other. The electrical length of the transmission line is al...
متن کاملLocking techniques for RF oscillators at 5-6 GHz frequency range
This work aims at analyzing three different techniques for synchronizing RF oscillators. These techniques are Injection Locking (ILO), Phase Locked Loop (PLL) and Injection Locked Phase Locked Loop (ILPLL). ILPLL, which is a combination of PLL and ILO, has superior noise performance –compared to all the restat medium frequency offsets and the same noise performance at low and high offsets. Furt...
