| Popis: | A digital-friendly approach to implement injection-locked ring oscillators is proposed. We show that lock can be achieved by dynamically switching the delay of a delay element in a ring oscillator. A logic gate that generates the control signal for switching the delay, together with a one-bit controlled oscillator, inherently realizes a locking mechanism. Measurement results from a prototype circuit fabricated with a 28 nm CMOS process demonstrate the feasibility of the concept. The circuit with a measured lock range of 2.4-3.7 GHz occupies an area of 0.00043 mm2 and consumes 0.18 mW power. |
