I am interested in an architecture that can provide a resolution of 12-14 bits and operate in the MHz range. I think pipelined or delta-sigma converters (described the above book) should be able to meet these specifications.
See i have worked upon flash adc
i have worked in 10MHz range
but i have worked in 3bit adc resolution, higher than that is difficult to perform using flash adc
pipelined is a stack of flash adc its bulkier than flash and so is delta sigma i believe
but it is true that the resolution in pipelined is better than flash
flash is simple as for a project work
Pipeline will be very difficult to achieve 12bit and even more difficult for 14 bit, because of noise reasons. According to me, don't even consider it. Sigma-delta is perhaps the way to go. But you need the appropriate technology to achieve the frequency you want, up to a certain value. With fast technology, maybe even SAR will do the job.
BTW, flash adc is good for up to 5-6 bits, not 3bits.
