#CMT# #/CMT# 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). #CMT#USE : #/CMT# Device for supplying a periodic alternating signal i.e. reference signal, for a radiofrequency signal transmission system of global system for mobile communication (GSM) system. #CMT#ADVANTAGE : #/CMT# The device is realized on a same electronic circuit at reduced cost in an integrated manner for supplying different reference signal used by the circuit. The nanomagnetic oscillator has reduced encumbrance, so as to reduce total encumbrance of the device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a circuit diagram of a reference signal supplying device. AMP : Amplifier cmd : Control signal COM : Control module Osc1-OscN : Nanomagnetic oscillators S-REF : Reference signal S1-SN : Periodic signals MUX : Multiplexer 20 : Reference signal supplying device. |
