Abstract

Un circuito oscilador (10) para generar señales de oscilación primera y segunda relacionadas con cuadratura que tienen frecuencias iguales comprende un primer circuito de oscilación (VCO_I) configurado para generar la primera señal de oscilación que tiene una primera frecuencia controlable, un segundo circuito de oscilación (VCO_Q) configurado para generar la segunda señal de oscilación que tiene una segunda frecuencia controlable; y un controlador (100) configurado para habilitar y deshabilitar la oscilación de los circuitos de oscilación primero y segundo (VCO_I, VCO_Q) y para controlar las frecuencias controlables primera y segunda, de manera que cuando se habilita la oscilación, se controlan las frecuencias controlables primera y segunda para ser inicialmente desiguales y luego volverse iguales.
