A switched-capacitor compatible membership function block

A new membership function block suitable for the switched capacitor (SC) te chnique is proposed, The circuit is based on an offset insensitive SC ampli fier and presents triangular shape transcharacteristics, Thanks to the SC a pproach, good precision independent of process tolerances is achieved. The proposed implementation was realized in a 1.2-mum standard CMOS technology. Both simulation and experimental data showed good agreement between expect ed and measured values.
