Top-Down, Constraint-Driven Design Methodology Based Generation of n-bit Interpolative Current Source D/A Converters
Abstract:
To accelerate the design cycle for analog circuits and
mixed-signal systems, we have proposed a top-down, constraint-driven
design methodology. In this paper we present
a design which demonstrates the two principal advantages that this
methodology provides-- a high probability for first silicon which meets all
specifications and fast design times. We examine the design of three
different 10-bit digital-to-analog (D/A) converters beginning from their
performance and functional specifications and ending with the testing of
the fabricated parts. Critical technology mismatch information
gathered from the testing phase is provided.
