Open the CIPO recordAbstract From the Canadian patent
This invention concerns a voltage control type variable resistor using a metal oxide semiconductor (MOS) and other metal insulated semiconductors (MIS) wherein an offset gate MIS transistor having smaller threshold voltage and a self-aligned gate MIS transistor having a larger threshold voltage than that of said offset gate MIS transistor in absolute value are formed in parallel on one insulated substrate. The sources the drains and the gates of both transistors are connected in common. A voltage control type MIS variable resistor described above can be improved, to have a wider linear range of resistance and voltage.

Why it's free to use
- Granted February 18, 1986. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended February 18, 2003.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
