ABSTRACT:
A trimmable semiconductor device includes a plurality of capacitors or resistors, each of which has a predetermined value, and a plurality of programmable switches each of which is operatively associated with the corresponding one of the plurality of capacitors or resistors. All of the capacitors or resistors and the programmable switches are fabricated internally and thus on the same chip or substrate. Thus, when the plurality of programmable switches are selectively programmed, the corresponding ones of the plurality of capacitors or resistors are selected and thus connected to a circuit formed on the substrate, thereby carrying out required adjustments electrically.
