This book describes using theory, SPICE simulations and chip measurements a new class of real time reconfigurable UV-programmable floating-gate ("FG-") circuits operating in subthreshold, implemented in a standard CMOS. A design method based on using the same basic two-MOSFET circuits extensively is proposed, meant for improving the opportunities to make larger FGUVMOS circuitry than previously. By using the same basic circuitry, instead of different circuitry for basic digital functions, one may ease UV-programming and test and save circuitry on chip and I/O-pads. Compact...
