In the November issue of Analog Dialogue we present Part 3 of our ongoing series on software-defined radio, covering validation of the system algorithm using live data as input and some powerful software and system development tools provided by ADI, MathWorks, and Avnet. If you’ve read Parts 1 & 2, you’ve seen this SDR system steadily progress from initial prototyping toward a production design. This radio will soon be ready for its real-world test drive, so stay tuned (pardon the pun). The second article revisits an earlier design of a versatile, low power single-ended–to–differential converter circuit. This time around, this useful converter circuit is made even more versatile. The authors have addressed using the circuit in applications that require greater output dynamic range, such as in signal conditioning temperature and pressure sensor outputs. They also explain how to implement an adjustable common mode which is very convenient when interfacing signals to some ADCs where the reference determines its full-scale range.
