Ultra-low power crystal oscillator |
摘要 |
An ultra-low power crystal oscillator architecture that draws less than 2 muA during steady state operation. An amplifier stage is self biased and has input and output clamp circuits that limit its signal swing. Circuit values are selected such that there is sufficient transient load current for the first amplifier stage to oscillate, while at the same time the input and output clamp circuits maintain a sufficiently low swing of the stage such that the steady state average load current is on the order of less than 1 muA.
