Abstract :
A new membership function block suitable for the switched capacitor (SC) technique is proposed. The circuit is based on an offset insensitive SC amplifier and presents triangular shape transcharacteristics. Thanks to the SC approach, good precision independent of process tolerances is achieved. The proposed implementation was realized in a 1.2-μm standard CMOS technology. Both simulation and experimental data showed good agreement between expected and measured values.
