I'll go Igor Alexander at London U WISARD and Carver Mead "Analog VLSI & Neural Systems"

WISARD did facial recognition at 30fps using lots of small digital neural nets (excellent hardware, not very good business plan).

Carver Mead's CalTech group used CMOS transistors in analogue modes (Voltage controlled current switches IIRC) to give the massive dynamic range that human hearing and eyesight have. "The Silicon Eye" and "Nano" describe his group, and some of the events that may have ended it.

Sadly just old books on Amazon now.

BTW I'm not surprised the FPGA stopped working at a different temperature. Analogue systems are quite sensitive to "drift," usually ageing but also temperature effects.
