FPGA's can't do that (or at least one's mere mortals can buy), but Cypress have a line of parts called PSoC (programmable system on chip) which can effectively synthesize analogue cells like op-amps in an analogous way to an FPGA. They also have a cut-down (surprised?) version of verilog, so you can write a few CPLD-y verilog modules to go on it as well.
The dev boards are very reasonably priced, well worth having one around to play with - can't comment on using them at scale. Cypress have some pretty good video lecture/tutorials on using them by Alan Hawse (Who is very stereotype-engineer https://youtu.be/0IKuUgEWAqg)
