Abstract:
A wireless system includes an active oscillator and a front-end circuit. The active oscillator is used to generate and output a reference clock. The active oscillator includes at least one active component, and does not include an electromechanical resonator. The front-end circuit is used to process a transmit (TX) signal or a receive (RX) signal according to a local oscillator (LO) signal. The LO signal is derived from the reference clock.
