This oscillator has improved frequency stability and lower power dissipation by utilizing two transistors T8 and T10 of opposite conductivity type to drive the crystal. At zero crystal current the output resistance is low, and becomes lower with increasing current flow in either direction. Accordingly, a moderate bias current may be used without impairing frequency stability.
