stability of the cross-coupled transistor circuit
Oct 11^th, 2006, 7:34am

Hi,

Shall the stability of cross-coupled transistor circuit be checked? since this circuit is a positive feedback circuit, it's always instable? Such cross-coupled transistor circuit is often found in many applications, such as frequency dividers, shall a designer ensure that cross-coupled transistor circuit stable? It's really confusing

You might want to clarify a bit please, a simple schematic would be great! tnx, Jerry
