Abstract
A compensation system for a crystal oscillator including a DC level comparator, current compensation circuitry, and a compensation controller. The crystal oscillator includes an amplifier with a feedback resistance coupled between first and second terminals of a crystal resonator. The DC level comparator may be a hysteretic comparator that compares a DC level of the first node with a DC level of the second node and to provide a corresponding compensation signal. The compensation controller controls a magnitude and direction of the compensation current applied to the first node by the current compensation circuitry based on the compensation signal. The current compensation circuitry sources current to or sinks current from the first node until the leakage current is minimized. The compensation controller may include a digital counter the generates a digital control value used to activate selected current sources or sinks for developing the compensation current.
