Abstract :
Cascaded amplifiers pose a difficult problem with respect to stability calculations, especially in MMIC design. The common power supply can be a source of feedback between, rendering the initial stability calculations for each stage inaccurate. A new method to analytically determine the exact amount of allowable feedback before a circuit becomes potentially unstable is presented
