Abstract

Oscilador a cristal compensado en temperatura, que consta de un varactor de realimentación al cristal que modifica la frecuencia de oscilación en función de una tensión de control (V) que se aplique (T); un sensor electrónico de temperatura ambiente que envía su señal a medios electrónicos de compensación que constan de un circuito inversor de la señal de tensión procedente del sensor, un circuito no lineal que transforme la tensión procedente del sensor electrónico de temperatura en una función cúbica y un circuito que suma e invierte las señales procedentes del circuito inversos y del circuito no lineal para originar que dicha tensión de control se ajuste a la ecuación "V (T) = ko + k1 (T - Ta) + k2 (T - Ta) 3", siendo ko, k1, k2, constantes y Ta una temperatura de referencia predeterminada. De aplicación en radiofrecuencias.
