Appeal No. 1996-4200
Application No. 08/330,341
entered by the examiner (paper number 16). Accordingly,
claims 1 and 4 remain before us on appeal.
The disclosed invention relates to an integrated
comparator circuit.
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. An integrated comparator circuit, comprising:
first and second terminals for a supply voltage;
first and second input terminals;
first, second, third and fourth MOSFETs each having drain,
source and gate terminals and a transfer characteristic curve;
said first and second MOSFETs being connected in a series
circuit between said first terminal for the supply voltage and
said first input terminal, defining a node between said first
and second MOSFETs being connected to the gate terminal of
said fourth MOSFET;
said second input terminal being connected to said second
terminal for the supply voltage;
said third and fourth MOSFETs being connected to form and
[sic] inverter stage between said first and second terminals
for the supply voltage;
the transfer characteristic curve of said second MOSFET being
steeper than the transfer characteristic curve of said fourth
MOSFET;
said second and fourth MOSFETs each being an enhancement
MOSFET;
