Abstract: A low noise amplifier (LNA), formed as a monolithic
microwave integrated circuit (MMIC), includes a high-electron
mobility transistor (HEMT) and utilizes tunable
heterojunction bipolar transistor (HBT) active feedback to
improve the amplifier's gain-bandwidth and linearity
performance and to provide for self-biasing of the HEMT. In
addition to enhancing the self-biasing, the MMIC, in
accordance with the present invention, allows the frequency
bandwidth and linearity characteristics of the LNA to be
adjusted after the MMIC LNA has been fabricated without
significantly degrading the noise figure performance.

IPC: G06F17/50
Filed: 1997-08-26
Abstract: In a low power consumption circuit design method, a
timing analysis (Step S101) of a logic circuit is performed
and a delay time of a cell in a path having a timing slack
detected by the timing analysis is calculated when it is
replaced with a cell of a low voltage power source (Step
S108). When this replacement satisfies the timing
constraints, the cell is replaced with the cell of the low
voltage power source (Step S110). A cell in a path having
no timing slack detected by the timing analysis is replaced
with a cell having a higher driving ability (Step S115).
When this replacement of the cell satisfies the timing
constraints, the cell is replaced with a cell being
operable under the lower voltage power source (Step S110).

Abstract: A memory addressing circuit allows data stored in consecutive addresses
to be fetched simultaneously to improve the data transfer rate in a DRAM
system. In addition, the consecutive data may extend across blocks.
Specifically, the addressing circuit receives a signal indicating shift
up or shift down as input to a predecoder circuit and supplies a CARRY or
BORROW signal to a decoder. The decoder receives this signal, which
enables it to access a block higher or lower than a block corresponding
to an address designated by the original input address.

Abstract: Bags, primarily for liquid or other flowable products, are formed from sheet plastics material
to define a generally rectangular container closed at one end and with a filling and
discharging arrangement at the other end. The bags are formed from an outer sheet 10 and
an inner sheet 11, the outer sheet extending the full length of the bag whereas the inner sheet
extends only part way along the bag. The outer sheet defines pockets 15 which act as the
corners of the rectangle and the inner sheet extends across the comers of the rectangle and
is connected to the outer sheet adjacent the edges of the pockets. 
     The bag is made by feeding the two sheets of material onto a table, the outer sheet 10 lying
below the inner sheet 11. The outer sheet is drawn down to form the pockets 15 at spaced
locations along the table. The inner sheet is then welded to the outer sheet at 18, 19 adjacent
the edges of the pockets. The ends of the inner and outer sheets are then drawn over,
overlapped and connected together to form a tube and one end of the tube is closed to form
the base of the bag. The other end is the filling opening which can be closed after the bag is
filled.
