Open the CIPO recordAbstract From the Canadian patent
A mufti-stage amplifier utilizes capacitive nesting of three or more amplifier stages in combination with multiple feedforward paths to achieve frequency, compensation. Two stages (A M and A O) in cascade are first nested with a polesplitting, capacitor (C1) to form a stable device. A stable three-stage amplifier is then created by, nesting the two-stage device and a further stage (A I) with another polesplitting, capacitor (C2) where feed-forward paths are provided from the further stage to both of, the other stages.

Why it's free to use
- Filed February 7, 1992 and granted November 21, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 7, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 7, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
