【简 介】:Stability Considerations
When embarking on any amplifier design it is very important to spend time checking on the stability of the device chosen, otherwise the amplifier may well turn into an oscillator.
The main way of determining the stability of a device is to calculate the Rollett’s stability factor (K), which is calculated using a set of S-parameters for the device at the frequency of operation. The calculations are long winded and it is much quicker to simulate under ADS.
The conditions of stability at a given frequency are |Γin| < 1 and |Γout| < 1,and must hold for all possible values ΓL & ΓS obtained using passive matching circuits. We can calculate two Stability parameters K & |Δ| to give us an indication to whether a device is likely to oscillate or not or whether it is conditionally/unconditionally stable.
