crystal oscillator startup
Hi to all,
I'am working on crystal oscillator in classical Pirce configuration.
As an amplifier i use PMOS.
I want to ask if any of You know analytical relation between gm of the transistor and startup time of oscillator.
All books and articles say that startup time is dependent from Q of crystal and capacitances(or maybe i missed something). In my simulations i see that for higher biasing curent i have shorter startup time.
Wonder if any of You thought about that.
Best regards.
Marcin
