چکیده
Injection-locked oscillators (ILO’s) are investigated in a new theoretical approach. A first-order differential equation is derived for the noise dynamics of ILO’s. A single-ended injection-locked frequency divider (SILFD) is designed in a 0.5m CMOS technology operating at 1.8 GHz with more than 190 MHz locking range while consuming 3 mW of power. A differential injection-locked frequency divider (DILFD) is designed in a 0.5m CMOS technology operating at 3 GHz and consuming 0.45 mW, with a 190 MHz locking range. A locking range of 370 MHz is achieved for the DILFD when the power consumption is increased to 1.2 mW.

متن کاملFrequency synthesiser architecture eliminating high speed frequency dividers for millimetre-wave applications
A frequency synthesiser architecture for millimetre-wave applications is proposed. The architecture is based on a triple-push oscillator, which functions both as a divider and oscillator. Thus, the proposed architecture eliminates the need for injection locked frequency dividers that are the main contributors to the limited tuning capability of millimetre-wave phase-locked loops. Since the prop...
