Could anyone elaborate more on this ? Rp - 2/gm >= 0 or equivalently Rp >= |-2/gm| where |-k| = k , and k > 0 Click to expand... How to derive this start-up condition for oscillation ? Why with this above condition, the circuit has large swings ? Seems like it is opposite to **broken link removed**
