Application No. 09/498,559
for operating the circuit. Further details of this appealed
subject matter are recited in the appellant’s independent claims
1, 14 and 16 which read as follows:
1. A circuit for use as an active inductor on an integrated
circuit having a power supply voltage supplied at a first power
supply terminal, comprising:
an metal oxide semiconductor (MOS) transistor having a gate
terminal, a drain terminal, and a source terminal, said drain
terminal being coupled to said power supply voltage and said
source terminal being one of the terminals of said active
inductor; and
a resistor having a first terminal coupled to said gate
terminal and a second terminal coupled to a voltage that is
derived from said power supply voltage and has a larger absolute
value than said power supply voltage supplied at said first power
supply terminal and the same sign as said power supply voltage;
said circuit being adapted so that when said circuit is
operating said circuit behaves as an active inductor between said
source terminal and an other terminal of said active inductor on
said integrated circuit.
14. A circuit for use as an active inductor on an integrated
circuit, comprising:
a metal oxide semiconductor (MOS) transistor; and
a beyond voltage generator which generates a beyond voltage
that is either greater than the highest voltage or less than the
lowest voltage being supplied to said integrated circuit by a
power supply;
wherein said MOS transistor is coupled to said beyond
voltage generator so as to bias said MOS transistor with said
beyond voltage and said MOS transistor is adapted to operate as
said active inductor.
16. An integrated circuit comprising a metal oxide
semiconductor (MOS) transistor adapted to operate as an active
