Abstract

The lossless property of an MOS floating gate is exploited to implement exact summing operations in the charge domain. Lossless charge sharing in such structures yields circuits with potential applications as building blocks for analog-signal processing. A canonical structure, the Multiple Input Floating-gate Differential Amplifier is proposed and its use in different circuit configurations demonstrated. Experimental data from a multiple differential input operational amplifier are presented. Limitations of the proposed circuits are also discussed
