Injection-locked-oscillators (ILOs) have been used extensively because of their simple implementation and instantaneous locking characteristics. However, their application is hindered by their limited locking range compared with alternative techniques such as PLLs. In this project, PLL and injection locking elements are combined symbiotically to achieve wide locking range while retaining the simplicity of the latter.
