Abstract

This paper presents a programmable diffuser using floating-gate circuits. We present the dynamics of classical diffuser circuits and show the differences between the classical and the programmable case. Programmable diffusers offer man), advantages including removing individual element mismatch and also giving the user the ability to reconfigure the overall system behavior Programmable diffusers can be used for spreading, just as in a resistive network, and they can also be used to create applications based on wave propagation. Experimental data is presented from circuits fabricated on a 0.5 μm n-well CMOS process available through MOSIS.
