Periodic alternating signal i.e. reference signal, supplying device for global system for mobile communication system, has multiplexer receiving periodic and control signals and providing alternative signal based on value of control signal

摘要

The device (20) has a number of nanomagnetic oscillators (Osc1-OscN) providing periodic signals (S1-SN), where the number is higher than or equal to 2. A control module (COM) provides a control signal (cmd) with values, where each periodic signal is associated to one of the values of control signal. A multiplexer (MUX) receives the periodic and control signals, and provides an alternative signal equal to one of the periodic signals based on the value of the control signal. An amplifier (AMP) receives the alternative signal and provides an amplified signal i.e. reference signal (S-REF).
