1MHz PIERCE OSCILLATORS


Posted on Feb 5, 2014

Simple network design is a key feature of the Pierce circuit, as these 1-MHz oscillators illustrate.Operating the crystal slightly above resonance (Fig.21-5a) requires only one high-gain transistor stage.Operating it exactly at series resonance (Fig. 21-5b) requires an extra RC phase lag and two transistors which can have lower gain..
