How will you make that complex analog/digital circuit in volume?
Traditionally one would lay out a board. Maybe all or most of the digital bits can be stuffed into a field-programmable gate array (FPGA). The analog generally gets distributed via op amps, transistors, and passive components over the printed-circuit board. Crank up the volume and it might make sense to ASIC-ize the FPGA, but there's not much one can do to compress the analog.
Triad Semiconductor now offers an intriguing solution, a mixed-signal ASIC that is relatively cheap to produce.
The company sells ICs they call Via Configurable Arrays (VCA), which are nearly-complete ASICs. They're composed of "tiles" that contain standard components, such as all sorts of op amps, resistors, capacitors, data converters, and the like.
This is an interesting product concept, "via configurable arrays." They seem to have a decent amount of analog IP and I noticed they even have some high voltage and PMIC functions in one part and RF functions in another. Potentially very attractive for medium volumes.
