Dear all,
I have read the book - "Design of Analog CMOS Integrated Circuits" on page 499. It said that the LC crossed-coupled oscillator does not latch up because its low frequency gain is very small. Actually, I know that why the gain is low at the low frequency. However, why the low frequency is easier to latch up the circuit (as memory to store 1 or 0)? Could anyone answer me? It is because I am still trouble in the working mechanism about the cross-coupled oscillator. Actually, I know the DJ said that it is need to fulfill the Barkhausen criteria. However, how could I explain why this circuit will not stack at high or low?
thanks
