CIRCUIT DESIGN
All of our
circuit designers are qualified with several years of working
experience in electronics engineering. For every project, we assign
one of our senior design staff to communicate with your engineers to
determine the objectives of your project, establish some initial
parameters of the design, and open a channel of communication for
the transfer of information.
Circuits are
designed, starting with a written description of the objective. A
small list of several design approaches is created, including the
strengths and weaknesses of each. The potential design solutions are
internally analyzed and costed. A sub-set of the original list,
selected for their merit, is detailed and presented to the client
for review.
We then
create a general block diagram and break it down into small
functional circuits. These functional circuits may be broken down
again, into additional sub-circuits, depending on the complexity of
the signal paths and logic. Sub-circuits may include programmable
logic. Components are selected to satisfy the requirements of the
circuit, and schematics are created. The captured schematics can be
analyzed by circuit simulation and / or prototyping as required. The
small functional circuit schematics are then combined into a full
schematic representing the original block diagram. Again, the
captured schematic can be further analyzed by circuit simulation and
/ or prototyping as required.
