Appeal No. 1998-3036
Application No. 08/404,920
The disclosed invention relates to a circuit equipped with a signal receiver that can
be regulated by either analog or digital control voltages, and the resistive properties of the
circuit can be varied by connecting one or more control terminals of corresponding
transistors in groups.
Claim 1 is illustrative of the claimed invention, and it reads as follows:
1. A connecting arrangement presenting resistive properties and values, said
connecting arrangement comprising:
a plurality of transistor combinations connected between two conductors;
at least one control signal line, having an analog control voltage, connected to a first
group of transistors creating a first transistor combination, wherein said first transistor
combination is activated and deactivated in response to said analog control voltage on
said first control signal line, and
at least one second control signal line, having an analog or digital control voltage,
connected to a second group of transistors creating at least a second transistor
combination, wherein said second transistor combination is activated or deactivated in
response to said analog or digital control voltage,
wherein said analog control voltage and said analog or digital control voltage
provides an operating voltage point of each transistor in the first and second transistor
combinations approximately within a region where said each transistor in the first and
second transistor combination presents resistive properties.
