Appeal No. 96-3258
Application 08/241,875
Appellant has appealed to the Board from the examiner’s
final rejection of claims 4 to 10 and 13, which constitute all
the claims remaining in the application.
Representative claim 4 is reproduced below:
4. A low power, high speed driving circuit comprising:
a power terminal for connection to a power voltage
source;
a current source for providing current outputs including
a first current and a second current proportional to the first
current, the second current being input into the first
current;
a control circuit operably connected to said current
source and generating a control signal applied to said current
source;
said current source being initiated in response to the
control signal from said control circuit and being controlled
by said control circuit such that the sum of the first current
and the second current input into the first current is a
constant magnitude;
a switching element having input, output and control
terminals, the input terminal of said switching element being
connected to said power terminal, and the output terminal of
said switching element having a predetermined output potential
threshold; and
said switching element becoming conductive in response to
the input of the second current from said current source to
the control terminal thereof in dependence upon the potential
of said output terminal being lower than the predetermined
output potential threshold thereof.
