Title (EN) SYSTEMS AND METHODS FOR COMPENSATING FOR VARIATION IN AN AMPLITUDE-REGULATED OSCILLATOR
(FR) SYSTÈMES ET PROCÉDÉS PERMETTANT DE COMPENSER LES VARIATIONS DANS UN OSCILLATEUR À RÉGULATION D'AMPLITUDE
Abstract:
(EN) Circuits and methods for compensating variation in an amplitude-regulated oscillator are provided. In one example, the oscillator includes a diode clamp having back-to-back diode-connected transistors with body terminals. Circuits and methods modulate a body-source voltage of the diode-connected transistors to compensate for process, temperature, and voltage variation.
(FR) L'invention concerne des circuits et des procédés permettant de compenser les variations dans un oscillateur à régulation d'amplitude. Dans un exemple, l'oscillateur comprend un coupleur de diodes ayant des transistors connectés à des diodes dos à dos avec des bornes de corps. Des circuits et des procédés modulent une tension de source de corps des transistors connectés à des diodes pour compenser les variations de processus, de température et de tension.
