.~ Involving structure of three diverse function electrode type
DEFINITION
Classification: 330/309
Involving structure of three diverse function electrode type:
(under subclass 250) Subject matter wherein the semiconductor device is provided in three diverse-type electrodes for coupling the signal energy input and output, additional biasing or gain control, etc.., and the application of the controlled electrical energy source in which each electrode performs a distinct function.
(1) Note. If a claimed preferred embodiment of a patent application includes details of means to apply a variable electrical signal to an IC amplifying device, or details of means to utilize the output of an IC amplifying device, that application is properly classified elsewhere in this class.
(2) Note. If, however, a claimed preferred embodiment of a patent application is limited to details of an IC amplifying device without details of the input or output (utilization) means, or the input or output (utilization) means are recited in name only, then the application is properly classified elsewhere outside this class.
