Troubleshooting a 32kHz Crystal Oscillator

How to Actually Make it Oscillate? Now for an oscillator to work, we need an amplifier with a gain of greater than 1, and a phase shift of 360 degrees to get positive feedback. First problem – the transistor was saturated, with Vc stuck near 0V. For an oscillator to start noise...
