Abstract
Various aspects of an injection-locked oscillator and method for controlling jitter and/or phase noise are disclosed herein. In accordance with an embodiment, an injection-locked oscillator includes one or more circuits that are configured to receive a pair of complementary phase output signals from one or more gain stages of the injection-locked oscillator. The one or more circuits may be configured to receive one or more switching signals. The received pair of complementary phase output signals are shorted by use of the one or more received switching signals. The shorting reduces the phase difference between an input signal and an output signal of the injection-locked oscillator.
Claims19
An injection-locked oscillator, comprising:
- one or more circuits configured to:
- receive a pair of complementary phase output signals from a gain stage of said injection-locked oscillator;
- and
- a pair of shorting switches, arranged in parallel, and configured to:
- receive a pair of switching signals;
- and
- short, by said received pair of switching signals, said received pair of complementary phase output signals, wherein said short is configured to reduce a phase difference between an input signal and an output signal of said injection-locked oscillator.
A method for reducing jitter, said method comprising:
- receiving, by one or more circuits of an injection-locked oscillator, a pair of complementary phase output signals from a gain stage of said injection-locked oscillator;
- receiving, by a pair of shorting switches arranged in parallel, a pair of switching signals;
- and
- shorting, by said pair of shorting switches, said received pair of complementary phase output signals to reduce a phase difference between an input signal and an output signal of said injection-locked oscillator.
