LOW_FREQUENCY_PIERCE_OSCILLATOR

Published:2009/7/7 7:14:00 Author:May | From:SeekIC

The Pierce circuit oscillates at 4 kHz．At low frequencies，the crystal's internal senes resistance RS isquite high (45 K at 4 kHz）．Therefore，all FET-based source follower is included to prevent Q1 from loading the crystal output．
