Abstract: An integrated circuit resistor is provided that comprises a mesa 14 between electrical contacts 16 and 18. The electrical resistance between electrical contacts 16 and 18 is selectively increased through the formation of recesses 20 and 22 in the mesa 14. The size of recesses 20and 22 can be used to tune the value of the electrical resistance between contacts 16 and 18.

Abstract: According to one embodiment of the invention a method for switching an alternating current signal between at least two paths includes providing, in at least one of the paths, first and second field effect transistors in series. The method also includes providing a control voltage node operable to receive a control voltage and maintaining each of the first and second field effect transistors in pinch-off mode by offsetting a voltage on each gate of the field effect transistors with a DC voltage component other than the control voltage when it is desired for the alternating current not to flow through the at least one path.
